Eta Eridani (η Eridani, abbreviated Eta Eri, η Eri), officially named Azha (with a silent 'h', possibly / ˈeɪzə /), [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.
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 ...
Beta Eridani, traditionally called Cursa, is a blue-white star of magnitude 2.8, 89 light-years from Earth. Its place to the south of Orion's foot gives it its name, which means "the footstool". Theta Eridani, called Acamar, is a binary star with blue-white components, distinguishable in small amateur telescopes and 161 light-years from Earth.
Iota Eridani (ι Eri) is a solitary star in the constellation Eridanus. It is visible to the naked eye with an apparent magnitude of 4.11. [2] With an annual parallax shift of 0.02165 arcseconds, [1] it lies at an estimated distance of about 151 light years. This is an evolved giant star with a stellar classification of K0 III. [4]
Achernar is the brightest star in the constellation of Eridanus and the ninth-brightest in the night sky. It has the Bayer designation Alpha Eridani, which is Latinized from α Eridani and abbreviated Alpha Eri or α Eri. The name Achernar applies to the primary component [14] of a binary system. [5] The two components are designated Alpha ...
data. Tau2 Eridani (τ2 Eridani, abbreviated Tau2 Eri, τ2 Eri), formally named Angetenar / æŋˈɡɛtənɑːr /, [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.
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] It is relatively near to the Sun, with a ...
