Artist's Rendering of Exoplanet Orbiting Sun-like Star (image) Harvard-Smithsonian Center for Astrophysics Share Print E-Mail Caption This is an 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. Credit David A.
