two stars, two hot-Jupiters

both scorching planets of WASP-94 (Ab on the left, Bb on the right)

WASP-94, aka TOI-107, is a binary system consisting of two F-type main sequence stars. Both stars are each orbited by a hot-Jupiter: a transiting, puffy one for WASP-94 A (Ab= 18.85 Re, 143.65 Me) and a non-transiting one for WASP-94 B (Bb= 196.41 Me). WASP-94 joins a select few binary systems where each star is orbited by at least one planet.

PSR J0337+1715
An insane, ungodly exoplanetary system

PSR J0337+1715 is truly one of the weirdest exoplanetary systems known, and even one of the weirdest stellar systems in general. It's probably as far as you can get from something like the Solar System.

You got a pulsar orbited by a huge low mass white dwarf, then orbited by another ultracool white dwarf. And then on top of that there’s a candidate dwarf planet with the mass of the moon orbiting the entire triple stellar remnant system. I don't think there is any exoplanet system known which is quite as alien.

HD 13189
HD 13189

HD 13189 is an 8th magnitude star in Triangulum constellation.It has a spectral classification of K1II-III, making it a giant star that has evolved away from the main sequence. The mass is 1.2 times the Sun's, while measurements of the star's radius give estimates of 38 R☉. The atmosphere of the star displays short period radial velocity variations with a primary period of 4.89 days. This behavior is typical for giant K-type stars such as this and it is not the result of a close-orbit planetary companion.

HD 13189 b is an exoplanet or brown dwarf with mass ranges from 8 to 20 Jupiter mass. This object is located at a mean distance of 277 Gm (1.85 AU) from the star, taking 472 days to make one elliptical orbit.

Gliese 143(HD 21749)

HD 21749 is a K-type main sequence star (orange dwarf) with a spectral type of K4.5V, indicating it is smaller and cooler than the Sun. It is estimated to have a mass of 0.73 M, a radius of 0.70 R, and a luminosity of 0.20 L. Its effective temperature is 4,640 K, which gives the star an orange color typical of K-type stars. Its metallicity—the proportion of elements other than hydrogen and helium—is approximately equal to the Sun's.

The inner planet, HD 21749 c (the second in order of discovery), is orbiting the star at a distance of 0.08 AU with a period of just 7.8 days. A terrestrial planet, it has a radius of 1.1 R and was the first Earth-sized planet found by TESS. Its mass is too low to be calculated with current radial velocity data, with an upper limit of 3.5 M; a probabilistic model estimates it is most likely between 1 and 2 M.

The outer planet, HD 21749 b, orbits the star at a distance of 0.21 AU with a period of 35.6 days. With a mass of 20 M and a radius of 2.9 R, it is similar to Neptune but much denser. Its density of 4.7 g/cm³ suggests it is composed of a substantial rocky core, with a radius of approximately 2.1 R, plus a relatively thick gaseous layer.

COCONUTS-2 b, or WISEPA J075108.79-763449.6, is a gas giant exoplanet that orbits the M-type star L 34-26. With a mass of 6.3 Jupiters, it takes over one million years to complete one orbit around the star, and it is 7,506 AU away from it.

The planet was discovered in 2011 and was initially identified as a T9 free-floating brown dwarf WISEPA J075108.79−763449.6. During the COol Companions ON Ultrawide orbiTS (COCONUTS) survey, its association with L 34-26 was announced in 2021. At a distance of 10.9 pc, COCONUTS-2b is the closest directly imaged exoplanet to Earth known to date.

The researchers found that it is unlikely that COCONUTS-2b was formed inside the protoplanetary disk of the host star and it is more likely that the planet formed on its own via high entropy formation (aka hot-start process).

a red dwarf host to a hydrogen rich mini-Neptune

the three planets hosted by TOI-270

TOI-270, aka L 231-32, is a red dwarf located about 73.2848 lightyears from the solar system, it's orbited by three planets: a low-density super-Earth and two mini-Neptunes. TOI-270's planets have a small series of resonant orbits (b:c = 5:3 | c:d = 2:1). Additionally, TOI-270 d likely has a hydrogen rich atmosphere with it's strongest single light absorber likely being water, as revealed via a transit observation with Hubble.

Kepler Improvements for Project Sisyphus (KIPS)
Release 1

Over time, as this project has lingered on for, I took notice of the influx of various non-realistic looks addons for planets or those with low resolution textures. And as we approach Kepler's fifth year since it shutdown, I wanted to do something to honor the telescope responsible for not only the most amount of confirmed exoplanets, but also pioneering a new era of planet hunting.

the confirmed planets of Kepler-27, featuring their new textures

So I gathered a list of Kepler systems, from Kepler-4 to Kepler-100 and picked out the systems I believed should be redone, whether it be just retexturing them, adding new data, or both. Out of my list, 40 systems were chosen for remakes/updates:
Kepler-9, Kepler-10, Kepler-11, Kepler-13, Kepler-18, Kepler-19, Kepler-21, Kepler-23, Kepler-24, Kepler-25, Kepler-27, Kepler-28, Kepler-29, Kepler-30, Kepler-31, Kepler-32, Kepler-36, Kepler-38, Kepler-40, Kepler-41, Kepler-43, Kepler-44, Kepler-45, Kepler-46, Kepler-48, Kepler-50, Kepler-61, Kepler-63, Kepler-65, Kepler-67, Kepler-68, Kepler-76, Kepler-79, Kepler-80, Kepler-84, Kepler-87, Kepler-88, Kepler-89, Kepler-91, Kepler-97

an updated Kepler-10, with it's newly confirmed planet (Textures for all three object by John van Vilet)

The file download below contains every system mentioned in the list + their unconfirmed planets if they have them. A such, its quite large so if you don't want all of these systems, you can simply pick out what you want and delete the rest, or alternatively you can head to Celestia Mobi to find every system download listed individually.
