Eta Eridani (η Eridani, abbreviated Eta Eri, η Eri), officially named Azha (with a silent 'h', possibly / ˈ eɪ z ə /), [8] [7] is a giant star in the constellation of Eridanus. Based on parallax measurements taken during the Hipparcos mission, it is approximately 137 light-years from the Sun .
Omicron 1 Eridani (ο 1 Eridani, abbreviated Omicron 1 Eri, ο 1 Eri), also named Beid / ˈ b aɪ d /, [9] [10] is a variable star in the constellation of Eridanus. With an average apparent visual magnitude of 4.04, [3] it is visible to the naked eye on a clear, dark night. Based upon parallax measurements, it lies approximately 122 light-years ...
Tau 2 Eridani (τ 2 Eridani, abbreviated Tau 2 Eri, τ 2 Eri), formally named Angetenar / æ ŋ ˈ ɡ ɛ t ən ɑːr /, [8] [9] is a star in the constellation of Eridanus. It is visible to the naked eye with an apparent visual magnitude of 4.78. [2] The distance to this star, as determined via the parallax method, is around 187 light-years.
Lambda Eridani (λ Eri) is a star in the constellation Eridanus.It is visible to the naked eye on a dark night with an apparent visual magnitude of 4.27. The distance to this star, based upon an annual parallax shift of 0.00402 arcseconds, is roughly 810 light years.
The effective temperature of the outer envelope is about 8,104 K, [5] which gives the star a white hue typical of A-type stars. [20] The projected rotational velocity is a rapid 196 km s −1, [3] compared to 2 km s −1 along the Sun's equator. [21] The star is known to vary in apparent visual magnitude, ranging between 2.72 and 2.80. [22]
Delta Eridani, which is Latinized from δ Eridani, is the fifth-brightest star in the constellation of Eridanus.. The star is visible to the naked eye and has been observed to vary slightly in brightness between magnitudes 3.51 and 3.56, [2] although subsequent observations did not bear this out. [11]
