Beloved astrophysicist Neil deGrasse Tyson is no stranger to the world of comic book superheroes, having already found the location for Superman's home planet. He has now turned his keen scientific mind to the Marvel world and the issue of just how much Thor's mighty hammer weighs.

Thor's hammer Mjölnir is said to be made of neutron-star matter. Tyson did the calculations and determined the hammer must therefore weigh as much as 300 billion elephants. That's not a common form of weight measurement, so we have to do some further calculations to translate elephants into pounds.

• Tyson tweeted a photo of himself holding Thor's hammer along with the message, "Just an FYI: Thor was kind enough to lend me Mjölnir so that I could make the proper measurements."
  Tyson's ability to heft the overweight weapon may lead us to question his origin story of having been born in Manhattan. I'm starting to think we should look to a superhuman extraterrestrial source for Mr. Tyson.
  You can look to the stars to explain Tyson's affinity for Superman and Thor. "Always liked the fact that Superman & Thor are both Space Aliens, distinguishing themselves from most other superheroes," he tweeted.
