If you’re a science geek like me, you know who Neil deGrasse Tyson is. His approach to educating people about the Cosmos carries on the legacy of Carl Sagan, and his StarTalk radio show is a great listen. Today DC Comics is releasing Action Comics #14, and Tyson makes a guest appearance. Beyond just showing up in the issue, DC wanted some real science to link to the issue; so they asked him to locate a suitable star where Krypton could exist. Discover has the full details:
I won’t keep you in suspense: the star is LHS 2520, a red dwarf in the southern constellation of Corvus (at the center of the picture here). It’s an M3.5 dwarf, meaning it has about a quarter of the Sun’s mass, a third its diameter, roughly half the Sun’s temperature, and a luminosity of a mere 1% of our Sun’s. It’s only 27 light years away – very close on the scale of the galaxy – but such a dim bulb you need a telescope to see it at all (for any astronomers out there, the coordinates are RA: 12h 10m 5.77s, Dec: -15° 4m 17.9 s).
