An eclipsing binary star. They are actually two strongly flattened, almost equally sized stars that orbit each other in 2.051 days. As a result, we observe light changes of 68 Her from 4.7 mag to 5.4 mag. The brightness of both stars is quite different. The brighter one is 260 times more luminous than the Sun and the weaker one is only 100 times. Their mass reaches 7.5 times and 2.9 times the mass of the Sun. In terms of size, both stars exceed the diameter of the Sun by about 6 times.
