Tag: Exoplanets

A couple of years ago I wrote about the procedurally generated planets in Gaia Sky. In this post, I provided a more or less detailed technical overview of the process used to procedurally generate planetary surfaces and cloud layers.

Since then, we have used the system to spice up the planets in the planetary systems for which the Gaia satellite could determine reasonable orbits (see the data here, and some Gaia Sky datasets for some of those systems here, including HD81040, Gl876, and more).

However, with the upcoming Gaia DR4, the number of candidate exoplanets is expected to increase significantly, rendering the “one dataset per system” approach unmaintainable. In this post I describe some of the improvements made with regards to exoplanets in Gaia Sky, in both the handling of large numbers of extrasolar systems seamlessly, and in the brand new, improved procedural generation of planetary surfaces and clouds.
