LHS 2520, also known as GJ 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, [2] it has a surface temperature of 3024 K. [3] The star was too faint to have had its parallax measured by the Hipparcos satellite. Measurement by Gaia gives its parallax as 81.57±0.04 milliarcseconds, yielding a distance of 40 light-years (12 parsecs). [1]
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]
The star also appears as LP 734-32 in the 2014 game, Elite Dangerous. [7]
