There are 8 planets in our solar system. The order of the planets in our solar system, from the nearest to the sun to outwards is – Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune

  • Hence, Mercury is the closest planet to the Sun.
  • The temperature on Mercury varies extremely from 90 K to 700 K.
  • Mercury, the nearest planet to the sun, is the second densest major celestial body in space after our Earth.

The solar system includes the four inner planets, the asteroid belt, the four gas giants, and then and on to the Kuiper Belt. 

Mercury

Mercury is the nearest planet to the sun and is the smallest planet in the solar system. It moves around the sun in 88 days. 

  • The temperature at Mercury is extremely thin. 
  • It is mainly made of oxygen, sodium, helium, hydrogen, and potassium.
  • Its surface is filled with craters just like the moon.
