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 ...

A paper published in October 2021 determines, using absolute astrometry measurements from the Hipparcos, Gaia DR2 data, and new radial velocity measurements from Keck/NIRC2 Ms-band vortex coronagraph images, a lower absolute mass of 0.65 times that of Jupiter, at an eccentricity close to 0.055 with the planet orbiting at around 3.53 AU inclined ...
Kepler-452b (sometimes quoted to be an Earth 2.0 or Earth's Cousin [4] [5] based on its characteristics; also known by its Kepler object of interest designation KOI-7016.01) is a candidate [6] [7] super-Earth exoplanet orbiting within the inner edge of the habitable zone of the sun-like star Kepler-452 and is the only planet in the system discovered by the Kepler space telescope.
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 ...
