Comparing planets

in #space2 months ago

How many people can other planets feed?
Earth - 1
Venus - 1.722
Mars - 0.122
Moon - 0.074
Mercury - 0.979

I took numbers from the Nasa's sheet, divided diameter by the distance from the Sun and squared it, if it is any good measure of solar and wind power available at the surface.

So in summary 3.899 times Earth's population can live on terrestrial planets and the Moon.

As a sidenote:

Earth kicks butt at tidal power:

Earth - 1 + 2.17 from Earth-Moon interaction [2]
Venus - 0.056
Mars - 0.041
Moon - 0.002
Mercury - 2.430

mass / ( rotation period * distance from the Sun ^ 2 * inclination of equator to the ecliptic )

And probably at geothermal as well.

However, Earth has much less hydrogen for the fusion than the outer planets.

Earth - 1.487 * 10^11 kg

Jupiter - 1.423 × 10^27 kg

Saturn - 4.262 * 10^26 kg
