Question

Which planets are smaller than earth?

Answer 1

Size of planets:

1. There are eight planets in all. Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune are the planets.
2. Mercury is the smallest planet in our solar system, while Jupiter is the largest planet in our solar system.
3. The radius of the Earth's kilometers is $6,378\mathrm{km}$.
4. Mercury has a radius of $2,440\mathrm{km}$, which is roughly one-third the size of the planet Earth.
5. Venus has a radius of $6,052\mathrm{km}$, which is slightly less than the radius of the Earth.
6. Mars has a radius of $3,397\mathrm{kilometers}$, which is almost half the circumference of the planet Earth.
7. Jupiter's radius in kilometers is $71,492\mathrm{km}$, which is approximately 11 times the size of the Earth.
8. Saturn's radius in kilometers is $60,268\mathrm{km}$, which is approximately 9 times greater than the Earth.
9. Uranus' radius in kilometers is $25,559\mathrm{km}$, which is roughly four times the size of the planet Earth.
10. The radius of Neptune in kilometers is $24,766\mathrm{km}$, which is just slightly less than the Uranus radius.

Therefore, Venus, Mars, and Mercury are smaller than Earth.
