Epsilon Indi Ab is a gas giant exoplanet orbiting the star Epsilon Indi A, about 11.9 light-years away in the constellation of Indus. The planet was confirmed to exist in 2018. [ 1 ] It orbits at around 30 AU (almost as far as Neptune from the Sun) with a period of around 180 years and a relatively high eccentricity of 0.4, and has a mass ...

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 .
[1] [note 5] The star has a radial velocity of +15.5 km/s (35,000 mph) (away from the Sun). [100] The space velocity components of Epsilon Eridani in the galactic co-ordinate system are (U, V, W) = (−3, +7, −20) km/s , which means that it is travelling within the Milky Way at a mean galactocentric distance of 28.7 kly (8.79 kiloparsecs ...
It came within 7.0 ly (2.1 pc) of the Sun about 10,900 years ago and has been moving away since that time. [17] Kapteyn's Star is distinctive in a number of regards: it has a high radial velocity, [ 13 ] orbits the Milky Way retrograde , [ 16 ] and is the nearest-known halo star to the Sun. [ 18 ] It is a member of a moving group of stars that ...
