36.7 light-years from the Sun, Arcturus is a red giant of spectral type K1.5III—an aging star around 7.1 billion years old
that has used up its corehydrogen and evolved off the main sequence.

It is about the same mass as the Sun, but has expanded to 25 times its size and is
around 170 times as luminous. Its diameter is 35 million km.        Source: Wikipedia.
