How was the mass of the planets calculated

Planets - calculate masses

Calculator for the approximate mass of the sun, moon, earth and planets in kilograms and in comparison with each other. Kilogram is the SI unit of mass, for celestial bodies this unit is of course a bit small and thus leads to huge numbers. A yottagram (Yg, 1024 Gram, one quadrillion gram), equal to one exatonne (Et, 1018 Tons, a trillion tons) is more appropriate to represent this. The usual comparison values ​​for rocky planets are earth masses, for gas giants it is Jupiter masses and for stars, finally, solar masses.

Rounding to decimal places.

Please enter a value, the others will be calculated.

Very large and very small numbers are shown in e notation, e.g. 2e + 9 for 2 * 109 and 2e-9 for 2 * 10-9. If a value is displayed as 0 (e.g. for moon mass in solar masses), a higher number of decimal places is required.

Colloquially, the mass is also called weight, which is simply wrong for celestial bodies.

Example: Jupiter has more than 300 times the mass of the earth, but less than a thousandth of the solar mass.
