LHS 2520, also known as Gliese 3707, is a red dwarf star in the constellation Corvus. With an apparent magnitude of 12.12. it is too faint to be seen with the unaided eye. A cool star of spectral type M3.5V,[1] it has a surface temperature of 3024 K.[3] The star was too faint to have had its parallax measured by the Hipparcos satellite. Earth-based measurement gives its parallax as 77.93 ± 2.41 milliarcseconds, yielding a distance of 42 ± 1 light-years.[2]
In Action Comics #14 (January 2013), which was published 7 November 2012, Neil Degrasse Tyson appears in the story, in which he determines that Superman's home planet, Krypton, orbited LHS 2520. Tyson assisted DC Comics in selecting a real-life star that would be an appropriate parent star to Krypton, and picked the star in Corvus,[4][5] and which is the mascot of Superman's high school, the Smallville Crows.[6]
