82 Eridani
(Redirected from HD 20794)
The yellow dwarf star 82 Eridani is located 19.71 lightyears from the Solar system.[1]
Its mass is 85 percent that of Sol, our sun, and it is estimated it will remain on the main sequence for 15 billion years.[1]
It is orbited by multiple exoplanets.[1] One of its exoplanets, 82 Eridani d, dips in and out of the star's habitable zone.[2]

A bizarre exoplanet whose orbit takes it from the frozen wastelands of its planetary system to the inner edge of its habitable zone is challenging astronomers’ concepts of what kinds of planets can potentially support life.
