Can two stars orbit each other?

The answer

Binary star systems, where two stars orbit a common center of mass, are extremely common - estimates suggest over half of all star systems in the Milky Way are binaries or multiples. The two stars can orbit each other in periods ranging from under an hour to millions of years. In close binaries, one star can strip material from its companion, creating accretion disks and sometimes triggering nova explosions. The famous 'Tatooine' double sunset from Star Wars is not just fiction - the Kepler telescope has discovered multiple planets orbiting binary star systems, called circumbinary planets.
