The Solar System

The Solar system is the gravitationally bounded system of the sun and the objects that circumvent it.

Our Solar system consists of our star - the Sun and everything that gravitationally bounded with it - the globes Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune ; dwarf planet similar as Pluto ; dozens of moons ; and millions of asteroids, comets and meteoroids.

Our Solar system is in Milky Way Galaxy.

2. MERCURY

• A day on Mercury takes 59 Earth`s days.
• It is a rocky planet.
• Being so close to the sun, you might be strange that Mercury could harbor any surface ice at all.
