Earth mass

The mass of the Earth compares to Neptune as the mass of Neptune compares to Jupiter.

Earth mass (M_⊕) is the unit of mass equal to that of the Earth. 1 M_⊕ = 5.9722 × 10²⁴ kg.^[1][2] Earth mass is often used to describe masses of rocky terrestrial planets.

The four terrestrial planets of the solar system, Mercury, Venus, Earth, and Mars, have masses of 0.055, 0.815, 1.000, and 0.107 Earth masses respectively.

One Earth mass can be converted to related units:

• 81.3 Lunar mass (M_L)
• 0.003 15 Jupiter mass (M_J) (Jupiter is 317.83 x Earth mass)^[1]
• 0.0105 Saturn mass (Saturn is 95.16 x Earth mass)^[3]
• 0.0583 Neptune mass (Neptune is 17.147 x Earth mass)^[4]
• 0.000 003 003 Solar mass (M_s)
