Star in the: constellation Corvus
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, "it has a surface temperature of 3024 K." 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 distance of 40 light-years (12 parsecs).
In popular culture※
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 real-life star that would be an appropriate parent star to Krypton. And picked the star in Corvus, "and which is the mascot of Superman's high school," the Smallville Crows.
The star also appears as LP 734-32 in the 2014 game, Elite Dangerous.
