What is the weight of all the planets in the solar system?

Answer 1

1. Mercury - 5.43 gr/cm3
2. Venus - 5.24 gr/cm3
3. Earth - 5.515 gr/cm3
4. Mars - 3.940 gr/cm3
5. Jupiter - 1.33 gr/cm3
6. Saturn - 0.70 gr/cm3
7. Uranus - 1.30 gr/cm3
8. Neptune - 1.76 gr/cm3

Answer 2

• Mercury: 0.33×1024 kg - 0.055 Earths
• Venus: 4.87 x 1024 kg - 0.815 Earths
• Earth: 5.98 x 1024 kg
• Mars: 0.65 x 1024 kg - 0.107 Earths
• Jupiter: 1900 x 1024 kg - 317.8 Earths
• Saturn: 568 x 1024 kg - 95.152 Earths
• Uranus 868 x 1024 kg - 14.536 Earths
• Neptune: 102 x 1024 kg - 17.147 Earths

Answer 3

There are only 8 planets in the Solar System (that we know of, anyway).

My CRC Handbook of Chemistry and Physics (60th Ed.) lists the average densities as approximately (all in kg/m3):

Mercury: 5400

Venus: 5300

Earth: 5500

Mars: 3900

Jupiter: 1300

Saturn: 700

Uranus: 1600

Neptune: 2300

Answer 4

As weight is a function of gravity and mass it has no meaning outside the mass of an object.

The mass of all the planets is ~2700 x 10^24 kg
