I wonder if anyone can either answer the following or point me in the right direction for the answer?

How far apart are Epsilon Indi and Tau Ceti?

Thanks in advance.

The two stars and Sol create a very nearly equilateral triangle.

Normally, if you need to find out such information, you should find the angle between the stars on the sky from their measured celestial coordinates (right ascension and declination) as well as distances, build a triangle with that information and use basic trigonometry to get the length of the third side of the triangle.

If you're not familiar with celestial coordinates, it can prove a bit of a pain in the neck to get there, so you could instead use a planetarium software to do it for you.

The one I use is Celestia, and it's freely available on the net.

Thanks Bander. I'll look up Celestia.
