Best Eclipsing
Spica, designated Alpha Virginis, is the brightest star in the constellation of Virgo and a prominent binary star system. Located approximately 250 light-years from Earth, the system consists of two massive B-type stars orbiting so closely that their mutual gravity distorts them into ellipsoidal sha...
Alphecca, formally Alpha Coronae Borealis, is the brightest star in Corona Borealis, the Northern Crown, and lies about 75 light-years from the Sun. It is an eclipsing spectroscopic binary whose two stars orbit closely enough that the system periodically changes brightness when one component passes...
Sabik, formally designated Eta Ophiuchi, is a binary star system and the second-brightest star in the constellation Ophiuchus. The system is located approximately 88 light-years from Earth and consists of two white A-type main-sequence stars. These two stars orbit each other with an estimated period...
