Definition of Rasalgethi
astronomy
: a group of stars of the third magnitude that is seen in the constellation Hercules
Hercules resembles the constellation Orion but only has two stars along the belt (rather than three) and is not as bright as Orion but still recognizable. In Hercules, there is an interesting double star known as Rasalgethi, located above his head. — Chris Pagan, Tulsa World (Oklahoma), 5 June 2011
— called also Alpha Herculis
Note: What is visible in the night sky as the star Rasalgethi is actually a group of three stars bound together gravitationally; one red giant and a binary system of a yellow giant and a yellow dwarf star.
