Very small indeed. The distance between A and B was 400 au; the distance between B and C was 44 au. 40 Eridani (abbreviated 40 Eri), also designated Omicron² Eridani (ο² Eridani, abbreviated Omicron² Eri, ο² Eri), is a triple star system in the constellation of Eridanus.Based on parallax measurements taken during the Hipparcos mission, it is less than 17 light-years from the Sun. An Astronomical Unit is the distance between Earth and the Sun. The habitable zone of 40 Eridani A, where a planet could exist with liquid water, is near 0.68 AU from A.

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 165.02000 which gave the calculated distance to 82 Eridani as 19.77 light years away from Earth or 6.06 parsecs. This is shown below Dsitance (in trillion km) = 9.46 trillion km * (10.5) = 99.33 trillion kilometers 40 Eridani C is a red dwarf and also a flare star with the variable star designation DY Eridani. Given the relation that 1 light year = 9.46 trillion kilometers, and the distance from Epsilon Eridani to Earth which is 10.5 light years, we can solve for the distance between the star and Earth in light years by multiplying both values together. b.
