If Epsilon Eridani actually exisits, I think the distance is 10.5 light years.
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.
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.
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, NGC-5882 is more luminous
Sirius is actually a binary system.At a distance of 2.6 parsecs (8.6 light years), the Sirius system is one of our near neighbours.This equates to approximately:5 x 1013 miles8.1 × 1013 kilometres543,861 AU.
Epsilon Eridani b was created in 2000.
Epsilon Eridani is a galaxy in Halo books but one day somebody might name a planet after it.
"The Solar System". Any other system will be identified with the name of the primary star; for example, a hypothetical solar system around Epsilon Eridani would be called "the Epsilon Eridani system". (Epsilon Eridani is a star about 12 LY away which is very similar to our Sun.)
Outside of our solar system the nearest planet is 10.5 light years away orbiting the star Epsilon Eridani.
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.
There is no star with that name. Many stars have names that start with "Epsilon", followed by the genitive of a constellation, e.g. "Epsilon Cruxis", "Epsilon Geminorum", etc. If its epsilon segin cassiopeia, it is 520L/Y(light years) away from earth.
The exoplanet Epsilon Eridani b at about 10.3 light years from us.
There is no such thing as an "epsilon star". There are several stars that have "epsilon" in their names; basically one for every constellation, so "Epsilon" followed by the genitive for example, Epsilon Eridani, Epsilon Crucis, Epsilon Canis Maioris, etc.

Zeta Eridani (Zibal) is about 120 light years from us.
Neither Sirius A nor Sirius B have any known planets.
