How far is epsilon away from the earth?

Answer 1

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.

Answer 2

There is no "star Epsilon". Epsilon is the fifth letter of the Greek alphabet; as a result, there are lots of stars that have "epsilon" in their names - basically one for each constellation: Epsilon Eridani, Epsilon Cruxis, Epsilon Canis Majoris, Epsilon Orionis, etc.

Answer 3

There are several stars that include Epsilon in their name. Epsilon is the fifth letter in the Greek alphabet.
For example;
Epsilon Eridani is about 10.5 light years
Epsilon Aurigae is about 2,000 light years
Epsilon Bootis is about 203 light years

Answer 4

Please clarify what star you are talking about. Every constellation has a star called "Epsilon..." followed by the name of the constellation. The different "epsilon" stars are unrelated to one another.
