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 .
In many cases it is not possible to have an exact value, and an estimated range is instead provided. The coldest and oldest planet directly imaged is Epsilon Indi Ab, which has six times Jupiter's mass, an effective temperature of 275 K, and an age of about 3.5 Ga. This list includes the four members of the multi-planet system that orbit HR 8799.
An artist's rendition of Kepler-62f, a potentially habitable exoplanet discovered using data transmitted by the Kepler space telescope. The list of exoplanets detected by the Kepler space telescope contains bodies with a wide variety of properties, with significant ranges in orbital distances, masses, radii, composition, habitability, and host star type.
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 ...
The rapper’s song was transmitted at the speed of light — approximately 158 million miles — from Earth to Venus, which is Elliott’s “favorite planet.” Missy Elliott can now be heard in ...
Tadmor: The radial velocity variations of the star Errai were announced in 1989, consistent with a planet in a 2.5-year orbit. [5] However, misclassification of the star as a giant combined with an underestimation of the orbit of the Gamma Cephei binary, which implied the planet's orbit would be unstable, led some astronomers to suspect the variations were merely due to stellar rotation.
As it does every year, NORAD, the North American Aerospace Command, tracked Santa on his trip around the world on Christmas Eve so children and families could see where he was.
