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.

GJ 1289
a nearby red dwarf with a sub-Neptune companion

GJ 1289's sole sub-Neptune

GJ 1289 is a red dwarf located about 27.28 lightyears from the solar system. A single sub-Neptune mass planet was detected around this star with an orbital period of 111.74 days.

OGLE-2017-BLG-1170L
A tight pair of rogue Jupiters in the bulge

This addon adds OGLE-2017-BLG-1170L, the lens in the microlensing event OGLE-2017-BLG-1170. Located deep inside the galactic bulge, the binary system consists of a 3.06 Jupiter-mass planet and a 1.85 Jupiter-mass planet orbiting each other every 4 months at a separation of 0.08 AU, according to this 2019 paper anyway.
