Kuiper 90 is also known as 17 Lyrae C ( Gliese 747AB ), a red dwarf system near 17 Lyrae, but 26 light years from the Sun.

The extrasolar planets Gliese 876e, Gliese 876b and Gliese 876c are also in a 1: 2: 4 orbital resonance ( with periods of 124. 3, 61. 1 and 30. 0 days ).

It is also identified as Gliese 425, and in the past it was known as Abt's Star.

Luyten 726-8 ( also known as Gliese 65 ) is a binary star system that is one of Earth's nearest neighbors, at about 8. 7 light years from Earth in the constellation Cetus.

It is also known as Luyten 789-6 and Gliese 866 and all three components are M-type red dwarfs.

Wolf 359, also known as Gliese 406 and CN Leo, is a red dwarf of spectral class M6. 5 that emits X-rays.

For example, Gliese 436 can be interchangeably referred to as either Gl 436 or GJ 436.

Gliese 777, often abbreviated as Gl 777 or GJ 777, is a yellow subgiant approximately 52 light-years away in the constellation of Cygnus.

If a planet is sufficiently massive, the water on it may be solid even at high temperatures, because of the high pressure caused by gravity, as it was observed on exoplanets Gliese 436 b and GJ 1214 b.

* GJ 84. 3, entry in the Gliese – Jahreiß catalogue ( Preliminary Version of the Third Catalogue of Nearby Stars, W. Gliese and H. Jahreiss, 1991, CDS ID V / 70A.

* GJ 194, catalog entry, Preliminary Version of the Third Catalogue of Nearby Stars, W. Gliese and H. Jahreiss, 1991, CDS ID V / 70A.

The combined catalogue is now commonly referred to as the Gliese – Jahreiß ( GJ ) catalog.

Recently, the team of Stéphane Udry have discovered a new planet named Gliese 581 g, which is an extrasolar planet orbiting the red dwarf star Gliese 581.

For example, during the next 10 million years the known star with the greatest possibility of perturbing the Oort cloud is Gliese 710.

* 1994 – Gliese 229B is the first Substellar Mass Object to be unquestionably identified.

( The Laplace resonance in the Gliese 876 system, in contrast, is associated with one triple conjunction per orbit of the outermost planet.

Furthermore, the first speculated " habitable " planet discovered, Gliese 581 c, orbits a red dwarf star ( Gliese 581 ) located only 20. 3 light years from Earth — a notable similarity to the novel wherein Erythro is the first inhabited extra – solar body.

For example, the stars Gliese 644A and Gliese 644B form what appears to be a close visual binary star ; since Gliese 644B is a spectroscopic binary, this is actually a triple system.

The closest confirmed system is Gliese 832 at 14. 8 light years with one confirmed planet.

The closest multi-planet system is Gliese 876 at 15. 3 light years with four planets.

Gliese 581 is another well known red dwarf system which is speculated to have multiple planets within the habitable zone.

The principal investigator on HARPS is Michel Mayor who, along with Didier Queloz and Stéphane Udry have used the instrument to characterize the Gliese 581 system, home to one of the smallest known exoplanet orbiting a normal star, and two super-Earths whose orbits lie in the star's habitable zone .< ref name =" mayor ">

Gliese 876 is a red dwarf star approximately 15 light-years away from Earth in the constellation of Aquarius.

It is the third closest known star to the Sun confirmed to possess a planetary system ( after Gliese 674 and Epsilon Eridani ) and the closest such system known to consist of multiple planets.
