As an expert in the field of comic book physics and the lore of the Marvel Universe, I can provide an analysis of Thor's hammer-throwing capabilities. Thor, the Asgardian god of thunder, wields Mjolnir, a weapon that is not just a hammer but also a powerful magical artifact. The speed at which Thor can throw Mjolnir is not explicitly defined in the comics or movies, but we can make some educated guesses based on its performance.

In the Marvel comics, Mjolnir has been shown to move at speeds faster than sound when thrown by Thor. It is also capable of interstellar travel, meaning it can cover vast distances in the cosmos at incredible speeds. The hammer's speed is not just a result of Thor's physical strength but also its enchantment, which allows it to return to Thor's hand after being thrown, regardless of the distance.

And, I'll assume that Thor can spin his hammer as fast as a major league pitcher can throw��around 100 miles per hour or 45 meters per second. If you let go of a hammer spinning at 100 mph, it will fly off in a straight line (at least until gravity takes over) at that speed.read more >>
