Sun-like Stars Reveal Their Ages

  • Finder chart for one of the most Sun-like stars examined in this study. KIC 12157617 is located in the constellation Cygnus, about halfway between the bright stars Vega and Deneb (two members of the Summer Triangle). An 8-inch or larger telescope is advised for trying to spot this 12th-magnitude star.

  • Artist's conception of a hypothetical exoplanet orbiting a yellow, Sun-like star. Astronomers have measured the ages of 22 Sun-like stars using their spins, in a method called gyrochronology. Before now, only two Sun-like stars had measured spins and ages.
