The Epsilon Eridani planetary system also includes a debris disc consisting of a Kuiper belt analogue at 70 au from the star and warm dust between about 3 au and 20 au from the star. [ 23 ] [ 24 ] The gap in the debris disc between 20 and 70 au implies the likely existence of outer planets in the system.
Epsilon Eridani b, also known as AEgir , [4] is an exoplanet approximately 10.5 light-years away orbiting the star Epsilon Eridani, in the constellation of Eridanus (the River). The planet was discovered in 2000, and as of 2024 remains the only confirmed planet in its planetary system .
40 Eridani is the system's Flamsteed designation and ο² Eridani (Latinised to Omicron 2 Eridani) its Bayer designation.The designations of the sub-components – 40 Eridani A, B and C – derive from the convention used by the Washington Multiplicity Catalog (WMC) for multiple star systems, and adopted by the International Astronomical Union (IAU).
The 40 Eridani system is 16 light-years from Earth. p Eridani is a binary star with two orange components, 27 light-years from Earth. The magnitude 5.8 primary and 5.9 secondary have an orbital period of 500 years. [1] Artist's impression of a Jupiter-mass planet orbiting the nearby star Epsilon Eridani

In the southern-sky catalog Uranometria Argentina, 82 G. Eridani (often abbreviated to 82 Eridani) [9] is the 82nd star listed in the constellation Eridanus. [10] The Argentina catalog, compiled by the 19th-century astronomer Benjamin Gould, is a southern celestial hemisphere analog of the more famous Flamsteed catalog, and uses a similar numbering scheme. 82 G. Eridani, like other stars near ...
The closest encounter to the Sun so far predicted is the low-mass orange dwarf star Gliese 710 / HIP 89825 with roughly 60% the mass of the Sun. [4] It is currently predicted to pass 0.1696 ± 0.0065 ly (10 635 ± 500 au) from the Sun in 1.290 ± 0.04 million years from the present, close enough to significantly disturb the Solar System's Oort ...
