Project Sisyphus - Texturing/painting every exoplanet known

[Trolligi 112477]

This addon adds two hypothetical planetary systems around fast radio burst (FRB) sources - SGR 1935+2154, in the Milky Way, surrounded by the supernova remnant SNR G057.2+0.8 (also in this addon), and FRB 180916, located in the small spiral galaxy SDSS J015800.28+654253.0, located almost 500 million light years away in Cassiopeia. Two papers, authored by the same people, propose a planetary explanation for the fast radio bursts - the papers propose that they are created when a planet on an extremely eccentric orbit reaches periastron and is slightly disrupted, and the fragments that are ripped off the planet interact with the star, producing these bursts.

Paper - https://iopscience.iop.org/article/10.3847/1538-4357/ac558f (also proposes a system around FRB 121102, but since it's more than 2.5 Gly away, beyond the current 1 Gly render limit, I could not add it into Celestia)

Kepler-420
Kepler-420 is a binary star system, it takes 3430 ± 1200 days for these two stars to revolve around each other, and it is known that the host star A has a Jupiter-sized planet. It orbits its host star with a period of 86.647661 d ± 3 s and a high eccentricity of 0.772 ± 0.045.
