Rotating Question Curious About Astronomy? Ask an Astronomer

Can one star orbit another?

Is it possible for a sun the size of our own sun to orbit around Betelgeuse? Are there any stars that rotate around another star?

Absolutely. There are thousands upon thousands of known "Binary Stars," as they are called. In fact, most stars in our galaxy are in pairs or larger associations. Our sun, being alone with no stellar companion, is actually one of the exceptions.
