Epsilon Eridani is a target for planet finding programs because it has properties that allow an Earth-like planet to form. Although this system was not chosen as a primary candidate for the now-canceled Terrestrial Planet Finder , it was a target star for NASA's proposed Space Interferometry Mission to search for Earth-sized planets.

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 .
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.
The planet Epsilon Indi Ab was confirmed in 2018 [38] and formally published in 2019 along with its detection via astrometry. [11] A direct imaging attempt of this planet using the James Webb Space Telescope was performed in 2023, [39] and the image was released in 2024.
Astronomers have discovered a rare in-sync solar system with six planets moving like a grand cosmic orchestra, untouched by outside forces since their birth billions of years ago. The find ...
It is predicted, based on evolutionary models, to have a luminosity around to 6.31 × 10 −8 L ☉. [3] 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]
Hundreds of sub-Neptunes have been discovered. ... The planets orbit the star between 6% and 20% of the distance between Earth and the sun. ... The researchers hope the James Webb Space Telescope ...
Saturn’s rings are seen as viewed by NASA’s Cassini spacecraft, which obtained the images that comprise this mosaic at a distance of approximately 450,000 miles from Saturn April 25, 2007.
