Epsilon Eridani (Latinized from ε Eridani), proper name Ran, [17] is a star in the southern constellation of Eridanus. At a declination of −9.46°, it is visible from most of Earth's surface. Located at a distance 10.5 light-years (3.2 parsecs ) from the Sun , it has an apparent magnitude of 3.73, making it the third-closest individual star ...
In the southern-sky catalog Uranometria Argentina, 82 G. Eridani (often abbreviated to 82 Eridani) [9] is the 82nd star listed in the constellation Eridanus. [10] The Argentina catalog, compiled by the 19th-century astronomer Benjamin Gould, is a southern celestial hemisphere analog of the more famous Flamsteed catalog, and uses a similar numbering scheme. 82 G. Eridani, like other stars near ...
40 Eridani is the system's Flamsteed designation and ο² Eridani (Latinised to Omicron 2 Eridani) its Bayer designation.The designations of the sub-components – 40 Eridani A, B and C – derive from the convention used by the Washington Multiplicity Catalog (WMC) for multiple star systems, and adopted by the International Astronomical Union (IAU).
Theta Eridani is a binary system with some evidence suggesting it is part of a multiple star system. [7] [22] The main star, θ 1 Eridani, is of spectral class A4 with a +3.2 apparent magnitude. Its companion star, θ 2 Eridani, is of spectral class A1 with an apparent magnitude of +4.1. The angular separation of the two stars is equal to 8.3 ...
HR 1614 (284 G. Eridani, GJ 183) is a star in the constellation Eridanus. Based upon parallax measurements, it is about 28.8 light-years (8.8 parsecs ) distant from the Earth . [ 2 ] It is a main sequence star with a stellar classification of K3V. [ 3 ]
HD 17925 is a variable star in the equatorial constellation of Eridanus.It has the Gould designation 32 G. Eridani and the variable star designation EP Eri. The star has a yellow-orange hue and is dimly visible to the naked eye in good seeing conditions with an apparent visual magnitude that varies from 6.03 down to 6.08. [16]
β Eridani is the bright star towards the top (north). The brightest star, towards the lower left, is Rigel. In between is the reflection nebula IC 2118. Beta Eridani is the star's Bayer designation. It has the traditional name Cursa [4] [9] derived from Al Kursiyy al Jauzah, "the Chair (or "Footstool") of the Central One".
HD 10647 (q 1 Eridani) is a 6th-magnitude yellow-white dwarf star, 57 light-years away in the constellation of Eridanus. The star is visible to the unaided eye under very dark skies. It is slightly hotter and more luminous than the Sun, and at 1.75 billion years old, it is also younger. An extrasolar planet was discovered orbiting this star in ...
