Planets have
been around for thousands of years. They can be all different sizes, colours,
shapes and temperatures. All the planets orbit the sun. A few planets have been
visited by robots and cameras, but only Earth has human beings and animals.
The solar
system has 8 planets.
Mercury is
made of rock and dark orange lava. Iron is also what the core is made of. It is
the closest planet to the sun which makes it as hot as an oven! The distance
between Mercury and the sun is 58,000 million km. It is a very tiny planet that
is smaller than Earth’s moon. Mercury has been visited by robots and machinery
but people will never go there.
Uranus is
made of blue gas with tiny ice rings. 27 moons are on Uranus. It is the 7th
closest planet to the sun which is 2,870,972,200 km away. It is the third
biggest planet which is 47,150 km wide. Uranus takes 84 Earth years to orbit
the sun. Uranus can’t be seen
from Earth without a telescope.
Mars is made
of red rock with the highest mountains in the solar system! Mars is shaped like
an egg. It has two moons called Phobos and Deimos. Like all the planets, Mars
orbits the Sun. It can be seen with the naked eye. Mars takes 1 year and 9
months to get to from Earth.
