Eridani is a trinary system, three stars. Eridani B is a whit dwarf. A is an orange dwarf, and C is a red dwarf flare star.
If Epsilon Eridani actually exisits, I think the distance is 10.5 light years.
Acamar is spectral class A4, which makes it bluish-white.
Epsilon Eridani B is 10.4 light year away. There may be closer planets yet--I just glanced at the first half dozen in the exoplanet catalog. http://www.planetary.org/exoplanets/list.php?exo=Epsilon+Eridani+b CoRoT-Exo-1 B is about 1500 light years away, making it one of the furthest detected so far.
No, NGC-5882 is more luminous
Achernar (Alpha Eridani), sometimes spelled Achenar, is the brightest star in the constellation EridanusIt has a spectral class of B3V which means it's temperature is 10,000-30,000 K and it's colour will be blue white.
Epsilon Eridani b was created in 2000.
close to orange
Epsilon Eridani B is still unconfirmed, and details about it's size can only be speculative. Based on it's mass being about 1.5 that of Jupiter, it's diameter will be about the same, as gas giants do not increase in diameter with masses <1.6 MJ. Above this value the planet will shrink. So it's fair to say that Epsilon Eridani B will be the same size as Jupiter - give or take. See related question.
The exoplanet Epsilon Eridani b at about 10.3 light years from us.
The first white dwarf discovered was in the triple star system of 40 Eridani.
The first white dwarf star was discovered in 1783 by William Herschel. However, it was not called a white dwarfs until 1910, when Henry Norris Russell, Edward Charles Pickering, and Williamina Fleming studied the star further and used the term "white dwarf" to describe it.
If Epsilon Eridani actually exisits, I think the distance is 10.5 light years.
Zibal or Zeta Eridani is a Blue/White star of spectral type A5 approximately 120 light years away.
Eridani Sky Madera was born on December 29, 2007, in Allentown, Pennsylvania, USA.
Epsilon Eridani is a galaxy in Halo books but one day somebody might name a planet after it.
Chernar does not exist as a star but Achernar does.Achernar (α Eri, α Eridani, Alpha Eridani), sometimes spelled Achenar.
Zaurak or Gamma Eridani is a Red Giant star of spectral type M0.5 III Ca-ICr. It is approximately 150 ly from Earth.
