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 .
53 Eridani (abbreviated 53 Eri), also designated l Eridani (l Eri), is a binary star in the constellation of Eridanus. The system has a combined apparent magnitude of 3.87. Parallax estimates made by the Hipparcos spacecraft put it at a distance of about 110 light-years , or 33.7 parsecs , from the Sun .
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 ...
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]
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]
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.
58 Eridani is a main-sequence star in the constellation Eridanus. It is a solar analogue, [12] having similar physical properties to the Sun. The star has a relatively high proper motion across the sky, and it is located 43 light years distant. It is a probable member of the IC 2391 moving group of stars that share a common motion through space ...
