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 .
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.
Upsilon 2 Eridani (υ² Eridani, abbreviated Upsilon 2 Eri, υ 2 Eri), officially named Theemin / ˈ θ iː m ə n /, [10] [11] is a star in the constellation of Eridanus. It is visible to the naked eye with an apparent visual magnitude of 3.8. [2]
Pi Eridani, Latinized from π Eridani, is a star in the constellation Eridanus. It has an apparent visual magnitude of 4.40, [ 2 ] which is bright enough to be seen on a dark, clear night. Based upon parallax measurements, it is located roughly 480 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 ...
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]
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]
