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 8.8 AU with a period of around 29.9 years and a relatively high eccentricity of 0.48, and has a mass around 3 times that of Jupiter.[2] Direct imaging of this planet using the James Webb Space Telescope is planned.[4]
The Epsilon Indi system also contains a pair of brown dwarfs, Epsilon Indi Ba and Bb, at a wide separation from the primary star. As such, this system provides a benchmark case for the study of the formation of gas giants and brown dwarfs.[1]
