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]
