Yeah i knew those two from somewhere! J1217 is a T8.5/Y0, 30/22 MJup binary pair, and J0458 is a T8.5/T9.5, 15/10 MJup pair.

Pre-2009 Microlensers
The classic lensing systems


Welp here comes the first package. Pre-2009 Microlensers aka Early Years Microlensers if you hate fun contains all 7 systems and 8 briefly distorted worlds discovered before 2009. If it wasn't that obvious already.

This includes the following planetary systems:

MOA-2007-BLG-192L
MOA-2007-BLG-400L
OGLE-2003-BLG-235L
OGLE-2005-BLG-071L
OGLE-2005-BLG-169L
OGLE-2005-BLG-390L
OGLE-2006-BLG-109L

LTT 1445
A triple system hosting two earth-sized planets and a super-earth

I got my textures for Ac and Ab from universe sandbox. For Ad, since it's an ocean planet, I got the cloud texture from Cinema 4D because it was 5 months later and I got good at using Cinema 4D textures.

The two planets, A c and A b


A d

2MASS J1119-1137
A nearby sub brown dwarf binary containing a small mini-neptune in the current habitable zone of component A

J1119 A with its exoplanet in the foreground (I consider bodies around young sub brown dwarfs as planets, not moons)

Ross 458
A nearby T-type sub brown dwarf/planet orbiting a binary at a wide distance

Ross 458 b/Ross 458 C

HAT-P-11
Just another misaligned Hot Neptune, and a Super-Jupiter to boot


HAT-P-11, also designated Kepler-3 because it was visible in the Kepler field of view, is a K-type metal rich star in the constellation of Cygnus. It has a relatively large rate of proper motion, and it has an anomalously high fraction of helium inside it. Two planets orbit HAT-P-11, these planets being a misaligned Hot Neptune with a noticeably eccentric orbit, and a far-out Super-Jupiter that also has an eccentric orbit, albeit more intense. Again, not a particularly uncommon type of exoplanetary system.

A Saturn-esque planet orbiting an extremely active ultracool dwarf on the red-brown boundary

Note that I did a big oopsie by incorrectly defining the clouds. See an updated version below.

OGLE-2013-BLG-0341L

OGLE-2013-BLG-0341L is a binary star system consisting of two red dwarfs, with a cold, terrestrial-mass planet in orbit around the secondary star. It was the first cold terrestrial exoplanet discovered by microlensing, and the first overall outside of the PSR B1257+12 system. (Other cold terrestrial planets include TRAPPIST-1 h, GJ 3323 c, and OGLE-2016-BLG-1195L b.)

For this planet, I've simply reused an "exo-Titan" texture I had originally made for Barnard's Star b, a planet candidate which more recent research has shown likely doesn't exist. The surface texture is derived from one made by Gurren Lagann, also originally for Barnard's Star b. Gurren Lagann also created the stars' textures, specifically for this addon.

Kepler-11
The first discovered star system with six transiting planets

Kepler-11, also designated as KOI-157, is a Sun-like star about 2,148 light years away in the constellation Cygnus. Announced on February 2, 2011, the star system is among the most compact and flattest systems yet discovered. It is the first discovered case of a star system with six transiting planets. All planets are larger than Earth, with the larger ones being about Neptune's size

Kepler-138
Featuring the lowest-mass exoplanet ever discovered (as of 2022)

Kepler-138, also known as KOI-314, is a red dwarf about 218.5 light-years away in the constellation Lyra. The star hosts three confirmed planets, including the lowest-mass planet with a measured mass and size discovered to date, Kepler-138b, with a mass comparable to that of Mars. Kepler-138d is remarkable for being a gas dwarf despite being lighter than Earth, however in this addon, it is depicted as a terrestrial instead

Kepler-438
An Uninhabitable Earth-like exoplanet

Kepler-438, also known as KOI-3284, is a binary star system of two red dwarf stars about 587 light-years away in the constellation Lyra. The component A's only known planet was notable for initially being one of the most Earth-like exoplanets ever found, but subsequent studies by the researchers of the University of Warwick showed that the planet is subjected to powerful radiation activity from its parent star every 100 days, much more violent storms than the stellar flares emitted by the Sun. For this reason, the planet is certainly not habitable for life as we know it here on Earth. This addon depicts if Kepler-438 Ab is indeed a habitable Earth-like planet

I did a big stupid with TVLM 513-46546 b because I wrongly defined its clouds which caused them not to show up. Here is the fixed version with a pic of TVLM 513 b with clouds. Not much different though.

Kepler-444
An old planetary system with three Suns

Kepler-444, also known as KOI-3158, is a trinary star system consisting of a K-type main sequence star and two red dwarfs orbiting each other about 116.4 light-years away in the constellation Lyra. At 11.2 billion years old, the component A's system of five rocky planets is one of the oldest star systems ever discovered

82 G. Eridani
A Sun-like star accompanied by 3 or 7 planets

82 G. Eridani, also known as Gliese 139, is a Sun-like star about 19.7 light-years away in the constellation Eridanus. As of 2022, this star is home to at least three planets so far, in addition to four more waiting to be confirmed by further analyses. Take note that this version doesn't include a texture for the unconfirmed planet h

TrES-2 Ab (update)

An update with a new texture of my TrES-2 Ab addon, which I released several months ago. At the time, I knew practically nothing about working with textures. Now I know better. This update is much better than the old version, honestly.

If there is any problem with this addon, please let me know. But probably no problem, I've revised a lot.

Update (Aug-15): Fixed orbital parameters and added a night map.
