• The inner planets, namely Venus, Mercury, Earth, and Mars were formed from the metallic material that was there in the 'solar nebula'.

• The outer planets, viz. Jupiter, Saturn, Uranus, and Neptune were formed from the residual gaseous material left in the nebula.

• Out of the eight planets, Jupiter is the largest whereas Mercury is the smallest.

• 'Earth' is the only planet in the 'Solar System' known to host life and enveloped by a definite atmosphere.

• Venus is the 'second planet in the solar system' and is referred as the planetary sister of Earth.

• Saturn is the 'second-largest planet' in the solar system and is famous for its ring system.

• Uranus is called an ice giant and it also gets colder than any other planet in the solar system.
