Neighbouring Planets

The Solar System is but a small cul-de-sac in the suburbs of the unimaginably large city of the universe, yet is home to some of the most amazing wonders.

Home of the planets

Our planet is just one of 8 in our Solar System, yet is the only one currently capable of hosting life. The five planets outside of the Earth's orbit are (in order of distance from Earth's orbit) Mars, Jupiter, Saturn, Uranus and Neptune. The other two planets, Venus and Mercury, are within the Earth's orbit. The inner four of the eight planets (Earth included) are rocky planets, whereas the outer four planets are gas giants.

Do other planets have moons?

Yes! Every planet in the Solar System except for Mercury and Venus have moons! Jupiter has moons large enough that they can be seen from Earth using binoculars, the main four being Io, Europa, Ganymede and Callisto.
