A prominent astrophysicist has pinned down a real location for Superman's fictional home planet of Krypton.

Krypton is found 27.1 light-years from Earth, in the southern constellation Corvus (The Crow), says Neil deGrasse Tyson, director of the American Museum of Natural History's Hayden Planetarium in New York City. The planet orbits the red dwarf star LHS 2520, which is cooler and smaller than our sun.

Tyson performed the celestial sleuthing at the request of DC Comics, which wanted to run a story about Superman's search for his home planet.

The new book — Action Comics Superman #14, titled "Star Light, Star Bright" — comes out Wednesday (Nov. 7). Tyson appears within its pages, aiding the Man of Steel on his quest.

"As a native of Metropolis, I was delighted to help Superman, who has done so much for my city over all these years," Tyson said in a statement. "And it’s clear that if he weren’t a superhero he would have made quite an astrophysicist."

You'll have to read "Star Light, Star Bright" to find out just how Superman and Tyson pinpoint Krypton. For amateur astronomers who want to spot the real star LHS 2520 in the night sky, here are its coordinates:

Right Ascension: 12 hours 10 minutes 5.77 seconds

Declination:  -15 degrees 4 minutes 17.9 seconds

Proper Motion: 0.76 arcseconds per year, along 172.94 degrees from due north

Superman was born on Krytpon but was launched toward Earth as an infant by his father, Jor-El, just before the planet's destruction. After touching down in Kansas, Superman was raised as Clark Kent by a farmer and his wife.

Now Superman will apparently know exactly where he came from.

"This is a major milestone in the Superman mythos that gives our super hero a place in the universe," DC Entertainment co-publisher Dan DiDio said in a statement. "Having Neil deGrasse Tyson in the book was one thing, but by applying real-world science to this story he has forever changed Superman’s place in history. Now fans will be able to look up at the night’s sky and say, 'That’s where Superman was born.'"

   "...The planet orbits the red dwarf star LHS 2520, which is cooler and smaller than our sun...."
   
   So Tyson has identified a currently existing planet within this star system? But according to Superman lore, Krypton was destroyed shortly after Superman's departure. Seems to me that choosing a more exotic star system that might exhibit a more tumultuous recent history would have been more appropriate.

   I believe the quote should have been written in the past tense, referring to the fictional planet Krypton- not any actual planet in the real universe.
   
   I would assume the reasoning for picking that system was A)it had to be a red star, according to the Superman mythos, yet be one that conceivably could have humanoid-life supporting planets around it (probably ruling out red giants;and B)that it be close enough (assuming Superman's spaceship somehow used a FTL or space-warping drive) that Krypton might still be visible from Earth. Since the Superman in ACTION COMICS (which is set "5 years ago" from current DC stories, telling tales of when Superman was just starting his career) (there was a major continuity reboot a bit more than a year ago- the NEW 52, as it's called) is about 22-24 years old, so a star whose light is reaching us 27.1 years later would be about right- I imagine, at some point, Superman will actually observe Krypton's destruction, if only obliquely.
   
   All this is supposition on my part- I'm not currently reading the series, so I could be wrong about all of this. It's happened before.
