Jupiter and Saturn
Jupiter and Saturn : Jupiter and Saturn
Jupiter is the largest planet in the solar system and has the fastest rotation. Saturn is the second-largest planet surrounded by rings of ice-covered rock. Both are gas giants.
Jupiter :
If oil the other planets were combined into one, its moss would be less than half of Jupiter's. It is 1300 times larger than Earth.
Jupiter completes its rotation in less than ten hours. This speed results in strong winds and huge cloud bands. Strong storms develop when these bands of clouds meet. One hurricane known as the Great Red Spot has existed for over 300 years.
Saturn :
Like Jupiter, Saturn is made of hydrogen and helium gas. Saturn's rotation is almost as fast as Jupiter's. Saturn also has very strong winds reaching speeds that are 11 times faster than a hurricane on Earth. There are thousands of rings surrounding Saturn. Each ring contains pieces of ice and rock travelling in orbit around Saturn. The rings closer to the planet seem to hold larger pieces while the outer rings contain finer materials. Both Jupiter and Saturn have many satellites some discovered only very recently. Jupiter seems to have the most moons of any planet in our solar system — at least 62. Saturn has more than 30.
AMAZING FACTS about Our Solar System :
The inner solar system is separated from the outer by the asteroid belt.
The solar system is port of the Milky Way galaxy which is a barred-spiral galaxy.
There were 9 planets in the Solar System until 2006 when the International Astronomical Union decided that Pluto could no longer be considered a plonet due to its size being smaller than our moon.
If all the planets were joined together, the Sun would still be more than 700 times bigger. It contains over 99% of the solar system's mass.
It takes two million years for gamma rays produced in the core of the Sun to reach its surface.
The Sun is the largest object the solar system. It is about 332 950 times more mossive than Earth.
The relationship between the Sun and the Earth drives the seasons, currents in the ocean, weather and climate.
The Sun has been burning for about five billion years and will bum for another five billion.
If you stood on Venus, the atmospheric pressure would be the same as if you were 900 metres underneath an ocean on Earth.
Much of the surface of Venus, including craters, has been covered in lava from previous eruptions.
Mercury and Venus are the only two planets in our solar system that don't have moons.
Mercury has the greatest variation in surface temperature of any planet in the solar system — can be over 600 degrees Celsius.
Because there is no wind or rain on the Moon, any footprints left by the astronauts should remain for millions of years.
It is thought that Earth was hit by a lorge object and the debris that was ejected into space joined together to form the Moon.
The official Latin name for planet Earth is Terra. It is named after the Roman goddess of fertility and growth - Terra Mater.
The Moon is the only other planet or satellite in the solar system that humans hove set foot upon.
The length of each Martian season is almost twice as long as a season on Earth.
Mars has the least hostile environment of all the other planets in the solar system.
The surface area of Mars is approximately equal to that of Earth's dry land as Mars does not have any oceans.
Mars has two small moons. They have uneven shapes and may originally have been asteroids.
After the Sun, the Moon and Venus, Jupiter is usually the fourth brightest object in the sky.
Saturn is almost exactly the same as Jupiter, just smaller. The only striking difference is the rings around Saturn.
Saturn's rings are thought to be particles of an old moon which was smashed to pieces in a collision million of years ago.
Jupiter is made of hydrogen and helium gases which also make up the Sun. If Jupiter had been any bigger, it could have become a star.
It takes 84 Earth years for Uranus to complete one full orbit around the Sun.
The Kuiper Belt contains many comets, asteroids and other small bodies made largely of ice.
As its orbit is so for from the sun, Neptune receives very little heat - in fact the uppermost regions of its atmosphere are -218 degrees Celsius.
