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.
No, NGC-5882 is more luminous
The closest planet outside the solar system is Proxima Centauri b, which orbits Proxima Centauri, the closest star to the Sun. It is located about 4.24 light-years away from Earth in the Alpha Centauri star system.
No. A star's class on the main sequence is ultimately predetermined by its mass, so a star cannot change its position on the main sequence. Epsilon Eridani is about 82% the mass of the sun, which limits it to a lower rate of fusion and thus a lower temperature and luminosity than a G-type star like the sun. Epsilon Eridani's only change in class will come when it leaves the main sequence to become a red giant.
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 often described as having a reddish hue, primarily due to its relatively cool temperature compared to other planets. Its color is influenced by the composition of its atmosphere, which may contain gases that absorb certain wavelengths of light, giving it a distinct appearance. Additionally, the planet's surface conditions, such as mineral content, can further contribute to its overall color.
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.
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.
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.
