Owing to its fast rotational speed of 6,200 mph (9,977.9
kmph), Saturn bulges out at the equator, and flattens out at the poles, giving
it an oblate shape.
Saturn doesn’t have a solid surface. A giant gaseous
planet, it is mostly composed of hydrogen and helium, with small traces of methane,
ammonia, acetylene, ethane, propane and phosphine.
The planet is believed to have a small, rocky core,
surrounded by thick liquid metallic hydrogen layer and then another liquid
layer of helium-filled molecular hydrogen. This layer slowly transforms into
gas as altitude increases. Since it is mostly made of gas, Saturn is the least dense
planet in our solar system. So, if there was a swimming pool big enough to hold
all the planets, Saturn would float on water. In comparison, Earth and Mercury
would sink the fastest.
One of the windiest planets, the wind speed around
Saturn’s equator can go up to 1,118 mph (1,800 kmph). Compare that to Earth’s
mightiest winds, which can attain a maximum speed of 250 mph (400 kmph).
The planet has 53 marked moons, along with nine more
which are awaiting confirmation of discovery. Its largest natural satellite is
the Titan, which is larger than the planet Mercury. Only Jupiter has more moons
(63) than Saturn.
While Saturn itself might not be able to support life,
its Titan and Enceladus moons might be able to provide a favorable habitat for
microbial life, as inferred by scientist after studying their chemical
compositions.
Along with Mercury, Venus, Mars and Jupiter, Saturn is
one of the five planets which you can see with t he naked eye. However, to
observe its rings, you need to use a telescope.
Cooler than most other planets, Saturn has an average
temperature of -350° F (-212° C). The coldest temperature ever recorded on
Earth is -129° F (-89° C).
In 1610, Italian astronomer and physicist Galileo Galilei
was the first to see Saturn through a telescope. Seeing the rings, he thought
that they were the “ears,” or “handles” of the planet, or probably its moons
Since Saturn spins
on a tilt, it has seasons. The summers on the planet last for nearly eight
Earth years.
The planet is known for its incredibly high atmospheric
pressure – strong enough to squeeze gas into liquid. No human spacecraft
created to date would be able to withstand such pressure.
The planet was named after the Roman god of farming,
Saturn (illustrated), and is denoted by the god’s tool, a sickle.
It has 1.1 times more gravitational pull than Earth. For
example, if an athlete jumps 10 ft (3 meters) in the air here, he will be able
to make it to a maximum height of 9.4 ft (2.8 meters) on Saturn.
