3. INTRODUCTION
• We have 8 planets in our Solar system. All the planets circle around the sun. Solar system has
been made up in two parts,
01. Inner Solar system(Terrestrial)
These are closest to the sun. Inner solar system planets are,
Mercury, Venus, Earth and Mars.
They are rocky planets and made up mostly of iron.
02.Outer solar system
These are giant planets that located far from sun. Outer solar system
planets are, Jupiter, Saturn, Uranus, Neptune and Pluto.
They are made up mostly of gases and have no solid surface.
