Mu Herculis

Mu Herculis is a nearby star system about 27.4 light years from Earth in the constellation Hercules. Its main star, Mu Herculis A (possibly a binary) is fairly similar to the Sun although more highly evolved. Its mass is about 1.1 times that of the Sun, and it is beginning to expand to become a giant. Mu Herculis A and the binary itself pair B-C are separated by 286 AUs. On the other hand stars B-C are separated by 11.4 AUs. Their orbit is quite ... more
