• sun's radius = 696 000 km
• sun's mass = 1.99 x 1030 kg

the distance between the sun and the earth is 23 000 bigger than the earth's radius

• earth's radius = 6378 km
• earth's mass = 5.97 x 1024 kg

the distance between the earth and our moon is 60 times bigger than the earths radius

• moon's radius = 1738 km
• moon's mass = 7.35 x 1022 kg

the planets in our solar system vary massively in size. mercury, the smallest planet, has a radius of 285 times smaller than the…
