Planets relative diameter?

Question

What are all the planets reletive size compared to earths. for example jupiter is 10x bigger than the earth and the sun is 100x bigger than earth.

Answer 1

If Earth is taken as ONE unit then planets have the following relative sizes and mass in the comparison of Earth.

1) Mercury = It is Smaller than the Earth with relative size only of 0 . 38 that of earth and the mass is only 0 . 055 that of earth.

2)Venus = Smaller than Earth. Size = 0 . 95 and mass = 0 . 815

3)Mars = Smaller than Earth. Size = 0 . 53 and mass = 0 . 11

4) Jupiter = Much larger than Earth. Size = 11 . 38 and mass = 317.9

5) Saturn = Larger than earth but smaller than Jupiter. Size = 9 . 45 and mass = 95 . 2

6) Uranus or Herschel = Larger than Earth but Smaller than Saturn. Size = 4.01 , mass = 14.6

7) Neptune = Smaller than Uranus . Size = 3.96 mass = 17.2

8) Pluto = The smallest of all . Size = 0.18 Mass = 0.002

Answer 2

You have to be careful with relative size. I think the sizes you are refering to are volumes not diameters. For example, If a sphere has three times the diameter, it has 9 times the volume.

This link provides diameters of all the planets.
