kauri tree
Kauri tree Why a people trying to kill the Kauri were prolific in the past
Kauri forests once covered 1.2 million ha from the Far North of Northland to Te Kauri, near Kawhia and were common when the first people arrived around 1,000 years ago.
Past uses of kauri
Maori used kauri timber for boat building, carving and building houses. The gum was used as a fire starter and for chewing (after it had been soaked in water and mixed with the milk of the puha plant).
The arrival of European settlers in the 1700s to 1800s saw the decimation of these magnificent forests. Sailors quickly realised the trunks of young kauri were ideal for ships' masts and spars, and the settlers who followed felled the mature trees to yielded huge .

Saturn is sometimes called "The Jewel of the Solar System." It is a planet that is nothing like our own. Humans have been gazing up at Saturn for a long time. They have been wondering about it for thousands of years.

Here are some fun facts about the Ringed Planet.
- Saturn is huge. It is the second largest planet in our Solar System. Jupiter is the only planet that is bigger.
- You cannot stand on Saturn. It is not like Earth. Saturn is made mostly of gases. It has a lot of helium. This is the same kind of gas that you put in balloons.
- Its beautiful rings are not solid. They are made up of bits of ice, dust and rock.

Some of these bits are as small as grains of sand. Some are much larger than tall buildings. Some are up to a kilometer (more than half-a-mile) across.
The rings are huge but thin. The main rings could almost go from Earth to the moon. Yet, they are less than a kilometer thick.
Other planets have rings. Saturn's rings are the only ones that can be seen from Earth. All you need is a small telescope.

Saturn could float in water because it is mostly made of gas. (Earth is made of rocks and stuff.)
It is very windy on Saturn. Winds around the equator can be 1,800 kilometers per hour. That's 1,118 miles per hour! On Earth, the fastest winds "only" get to about 400 kilometers per hour. That's only about 250 miles per hour.
Saturn goes around the Sun very slowly. A year on Saturn is more than 29 Earth years.
Saturn spins on its axis very fast. A day on Saturn is 10 hours and 14 minutes.
The Ringed Planet is so far away from the Sun that it receives much less sunlight than we do here on Earth. Yes, the Sun looks smaller from there.
The day Saturday was named after Saturn.
SIZE OF SATURN COMPARED TO THE EARTH
Side by side comparison of the size of Saturn vs EarthFACTS ABOUT SATURN
- Saturn is the sixth planet from the Sun, and last of the planets known to ancient civilizations. It was known to the Babylonians and Far Eastern observer.
- Saturn is one of five planets able to be seen with the naked eye. It is also the fifth brightest object in the solar system.
- In Roman mythology Saturn was the father of Jupiter, king of the gods. This relationship makes sense given that the planets Saturn and Jupiter are similar in so many respects, including size and composition. The Greek
- The most common nickname for Saturn is “The Ringed Planet”, a nickname arising from the large, beautiful and extensive ring system that encircles the planet. These rings are mostly made from chunks of ice and carbonaceous dust. They stretch out more than 12,700 km from the planet but are only a mere 20 meters thick.
- Saturn gives off more energy than it receives from the Sun. This unusual quality is believed to be generated from the gravitational compression of the planet combined with the friction from large amount of helium found within its atmosphere.
- It takes Saturn 29.4 Earth years to orbit the Sun. This slow movement against a backdrop of stars led to the planet being nicknamed “Lubadsagush” – or “oldest of the old” – by the ancient Assyrians.
- Saturn has the fastest winds of any other planet in our solar system. These winds have been measured at approximately 1,800 km per hour (1,100 miles per hour).
- Saturn is the least dense planet in the solar system. It is made mostly of hydrogen and has a density which is less than water – which technically means that Saturn would float. The layers of hydrogen get denser further into the planet, eventually becoming metallic and leading to a hot interior core.
- Saturn has 150 moons and smaller moonlets. All of these moons are frozen – the largest of which are Titan and Rhea. The moon Enceladus also appears to have an ocean hidden below its frozen surface.
- Saturn’s moon Titan is the second largest moon in the Solar System, behind Jupiter’s moon Ganymede. It has a complex and dense atmosphere made mostly of nitrogen and is composed from water ice and rock. The frozen surface of Titan has liquid methane lakes and a landscape which is covered with frozen nitrogen. It is possible that Titan may be a harbour for life – but that life would not be similar to life on Earth.
- Saturn is the flattest of the eight planets. With a polar diameter that is 90% of its equatorial diameter, Saturn is the flattest of all the planets. This is because of the planet’s low density and fast rotation speed – it takes Saturn 10 hours and 34 minutes to turn on its axis.
- Saturn has oval shaped storms which are similar to those of Jupiter. Scientists believe that the hexadiagonal-shaped pattern of clouds around Saturn’s north pole may be a wave pattern in the upper clouds. There is also a vortex over the south pole which resembles hurricane storms on Earth.
- Saturn appears a pale yellow color because its upper atmosphere contains ammonia crystals. Below this top layer of ammonia ice are clouds that are largely water ice. Even further below that are layers of sulfur ice and cold hydrogen mixtures.
- Saturn has been visited by four spacecraft. These are Pioneer 11, Voyager 1 and 2 and the Cassini-Huygen mission. Cassini entered into orbit around Saturn on July 1, 2004 and continues to send back information about the planet, its ring and many moons.
- The magnetic field on Saturn is slighter weaker than Earth’s magnetic field. Saturn’s magnetic field strength is around one-twentieth the strength of Jupiter’s
- Saturn is known as a gas giant, but scientists believe it has a solid rocky core surrounded by hydrogen and helium
- Saturn and Jupiter combined account for 92% of the entire planetary mass in the solar system.
- The interior of Saturn is very hot, reaching temperatures of up to 11,700°C (21,000 °F).
- Saturn is 1,424,600,000 km from the Sun. This is around 0.9 billion miles.
MORE INFORMATION AND FACTS ABOUT SATURN
Other than Earth, Saturn is easily the most recognizable planet in the Solar System. The reason for this is obvious. Although the other gas giants possess a planetary ring system, none can match the size or beauty of the one found encircling Saturn.
Saturn is the last of the planets known to ancient civilizations. It is also one of the least understood in modern times. With theCassini-Huygens planetary mission that is currently underway, scientists hope to not only learn more about Saturn, but also Saturn’s moons and its planetary ring system.
ATMOSPHERE
Saturn’s atmosphere is composed of roughly 96% hydrogen and 4% helium, with trace amounts of ammonia, acetylene, ethane, phosphine and methane. It has a thickness of approximately 60 km. In the highest layer of the atmosphere, wind speeds reach1,800 km/h, easily some of the fastest in the entire Solar System.Although not as visible as those seen on Jupiter, Saturn does possess a horizontally banded cloud pattern. Furthermore, these bands are considerably wider near Saturn’s equator than those found at Jupiter’s equator. These cloud patterns were unknown until the Voyager missions beginning in the 1970s. Since that time, technology has increased to the point that Earth-based telescopes can now view them.
Another fascinating phenomenon that can be found in Saturn’s atmosphere is the appearance of great white spots. These are storms on Saturn, which are analogous to the Great Red Spotfound on Jupiter, though they are much shorter lived. TheHubble Space Telescope observed such a storm in 1990, though it was not present when the Voyager spacecraft had flown by in 1981. Based on historical observations, it appears that these storms are periodic in .INTERIOR
The interior of Saturn is believed to be extremely similar to Jupiter’s in the composition of its three layers. The innermost layer is a rocky core between 10-20 times as massive as the Earth. The core is encased in a layer of liquid metallic hydrogen. The outermost layer is composed of molecular hydrogen (H2). The only significant difference between the interiors of Saturn and Jupiter is thought to be the thickness of the two outer layers. Whereas Jupiter has a metallic hydrogen layer of 46,000 km and molecular hydrogen layer of is 12,200 km, those same layers on Saturn have a thickness of 14,500 km and 18,500 km, respectively.
nature, occurring approximately once per Saturnian orbit.Saturn, like Jupiter, emits approximately 2.5 times more radiation than it receives from the Sun. This is due to the Kelvin-Helmholtz mechanism, which essentially creates energy through gravitational compression of the planet due to its enormous mass. However, unlike Jupiter, the total amount of energy emitted cannot be accounted for through this process alone. Instead, scientists have suggested that the planet generates additional heat through the friction of helium rain.
A unique feature of Saturn is that it is the least dense planet in the Solar System. Although Saturn may have a dense, solid core, the large gaseous outer layer of the planet makes its average density a mere 687 kg/m3. As result, Saturn is lighter than water.
ORBIT & ROTATION
The average orbital distance of Saturn is 1.43 x 109 km. This means that Saturn is, on average, about 9.5 times the distance from the Earth to the Sun. The result of such a long distance is that it takes sunlight about an hour and twenty minutes to reach Saturn. Moreover, given Saturn’s distance from the Sun, it has a year lasting 10,756 Earth days; that is, about 29.5 Earth years.
At .0560, Saturn’s orbital eccentricity is the third greatest behind Mercury’s and Mars’. The effect of this large eccentricity is a substantial distance between the planet’s perihelion (1.35 x 109

- Saturn is the second largest planet in our solar system and is another gas giant.
- Saturn has a small rocky core covered with liquid gas.
- It is surrounded by a system of rings that stretch out into space for thousands of kilometres.
- The rings are made up of millions of ice crystals, some as big as houses and others as small as specks of dust.

- Like Jupiter, Saturn has many moons which surround it.
- Saturn is not a peaceful planet. Storm winds race around the atmosphere at 800kmp/h.
- Saturn has a very strong magnetic field which traps energy particles resulting in high levels of radiation.

Saturn was the Roman name for Cronus, the lord of the Titans in Greek mythology. Saturn is the root of the English word "Saturday."
Saturn is the farthest planet from Earth visible to the naked human eye, but it is through a telescope that the planet's most outstanding features can be seen: Saturn's rings. Although the other gas giants in the solar system — Jupiter, Uranus and Neptune — also have rings, those of Saturn are without a doubt the most extraordinary.
Physical characteristics of Saturn
Saturn is a gas giant made up mostly of hydrogen and helium. Saturn is bigenough to hold more than 760 Earths, and is more massive than any other planet except Jupiter, roughly 95 times Earth's mass. However, Saturn has the lowest density of all the planets, and is the only one less dense than water — if there were a bathtub big enough to hold it, Saturn would float.
The yellow and gold bands seen in Saturn's atmosphere are the result of super-fast winds in the upper atmosphere, which can reach up to 1,100 mph (1,800 km/h) around its equator, combined with heat rising

Saturn spins faster than any other planet except Jupiter, completing a rotation roughly every 10-and-a-half hours. This rapid spinning causes Saturn to bulge at its equator and flatten at its poles — the planet is 8,000 miles (13,000 kilometers) wider at its equator than between the poles.
Saturn's most recent curiosity may be the giant hexagon circling its north pole, with each of its sides nearly 7,500 miles (12,500 km) across — big enough to fit nearly four Earths inside. Thermal images show it reaches some 60 miles (100 km) down into the planet's atmosphere. It remains uncertain what causes it.
Other titanic storms appear in Saturn’s atmosphere once every Saturn year (approximately 30 Earth-years), disrupting the temperature and winds of the planet’s skies. Six such storms have been observed on the planet since 1876, but in 2011, NASA’s Cassini spacecraft became the first orbiter to observe one.
Like other giant planets, Saturn also has northern and southern lights, caused by particles from the sun.

Saturn's moons
Saturn has at least 62 moons. Since the planet was named after Cronus, lord of the Titans in Greek mythology, most of Saturn's moons are named after other Titans, their descendants, as well as after giants from Gallic, Inuit and Norse myths.
Saturn's largest moon, Titan, is slightly larger than Mercury, and is the second-largest moon in the solar system behind Jupiter's moon Ganymede. (Earth's moon is the fifth largest.) Titan is veiled under a very thick, nitrogen-rich atmosphere that might be like what Earth's was long ago, before life. While the Earth's atmosphere extends only about 37 miles (60 km) into space, Titan's reaches nearly 10 times as far. The atmosphere contains a
