Epsilon Eridani (ε Eri / ε Eridani) is a main-sequence K2 class star in the constellation of Eridanus. It is the third closest star outside of the solar system visible without a telescope.

A young orange dwarf star in the constellation Eridanus that is visible to the naked eye and lies just 10.7 light-years away from the Sun. [C95]

[3688] epsilon Eridani, a main sequence star, is the third closest star that can be seen by the naked eye. It has at least one extrasolar planet, believed to be a gas giant similar to Jupiter. Being the nearest star similar to the Sun, only 10.
Naked-eye stars intrinsically fainter than the Sun are rare, the 61 Cygni pair and Epsilon Eridani fine examples.
A gas-giant planet orbits the star Epsilon Eridani in this artist's concept. Texas astronomers recently confirmed the planet, which is the closest extrasolar planet yet discovered, at a distance of 10.5 light-years.

The closest known extrasolar planet to the Sun lies around the star Epsilon Eridani, a star slightly dimmer and redder than the Sun, which lies 10.5 light years away. Its one confirmed planet, Epsilon Eridani b, is roughly 1.
Frank Drake, a young radio astronomer, pointed an 85-foot telescope at two nearby, Sun-like stars: Tau Ceti and Epsilon Eridani. Drake tuned the telescope to detect a frequency of around 1,420 MHz, the frequency at which atomic hydrogen emits.

Drake used a 25-meter-diameter radio telescope at Green Bank, West Virginia, to examine the stars Tau Ceti and Epsilon Eridani near the 1.420 gigahertz marker frequency.
In 1998, a dust ring, perhaps similar to the cloud of comets surrounding our own solar system, was discovered around the very young star epsilon Eridani.
EZ Aquarii is actually a triple system of red dwarf stars.
In 1960 he kicked things off by conducting a radio search of two stars, epsilon Eridani and tau Ceti, ...
