Earth-Like Design your planet

Fraction of the planet's surface covered by land (between 0 - 1). Earth value = 0.29

Rate of volcanism on the planet relative to the Earth (between 0 - 1000). Earth value = 1.0

Different types of star can be more or less luminous than the Sun.

Distance from the star in astronomical units [au] (value greater than 0). Earth value = 1.0 au

Planet building is a big job and this may take a minute.

Warning, planet designers!

This climate model is designed for a planet similar to our present-day Earth. For large changes in conditions, the surface temperature may become less accurate. The simulation also has a maximum run-time and risks not reaching equilibrium for very different worlds.
