Based on Mjolnir's dimensions and neutron star construction (the densest and heaviest material in the known universe), Roper estimates that the hammer weighs in at a thunderous 4,634,850,000,000,000 kilograms (that's nearly five quadrillion kg!).
For example, Marvel – which publishes the Thor comics – issued a “Thor's Hammer” trading card in 1991 that states Mjolnir is made of Uru and weighs precisely 42.3 pounds. That's lighter than a herd of 300 billion mice, much less a herd of 300 billion elephants.
Thor OdinsonThor. The son of Odin uses his mighty abilities as the God of Thunder to protect his home Asgard and planet Earth alike. Thor: 640 lbs., Donald Blake: 150 lbs.
And the comic claim that Mjölnir is made out of Uru, a metal that only comes from Asgard. Make-believe metal is kind of hard to weigh. But then, in 1991, Marvel released a "Thor's Hammer" trading card that claims that Mjolnir weighs precisely 42.3 pounds.
God of War's combat is impressive, and while Mjolnir could have been a worthy addition to Kratos' arsenal, it wouldn't fit the character's arc based on William's logic. The Norse Saga has transformed Kratos from a ruthless and bloodthirsty anti-hero to a protagonist with real depth.
While it is true that the hammer would have been an incredible asset for the player, it cannot be wielded or even picked up by Kratos (nor Atreus) for several reasons.
Godlike strength: Thor has limitless strength and can power himself even more by charging himself with lightning. He was able to bend Captain America's shield, then bend it back perfectly back to shape. He's the second strongest Avenger. He is the mightiest.
Thor: 3,500 lb.
Assessing Thor's strength might be even harder than the Hulk. Basing it off his pitches with the hammer Mjolnir won't help us either; the mystical mallet's weight is a mystery, and while we can't be sure, it seems to be psionically connected to him, flying where he wants.
He Doesn't Need Sleep, Food, Or Even A Breath Of Air
In a major advantage over pretty much everyone, Thor has absolutely no need to sleep, no need to eat, and no need to breathe.
The amazing thing about the Hulk is that unlike nearly every other superhero ever created, the Hulk's strength has absolutely no upper limit. He can lift a commercial airplane – which weighs around 100 tons – when he is at his calmest; that's no problem for him.
Thor / Odin
In the comics, The Norse God of Thunder can destroy planets, control the weather (including summoning lightning bolts), fly through space at the speed of light, and even break adamantium. That's right, Thor could smash Wolverine's metal skeleton if he wanted to. He has beyond class 100 strength.
Tungsten Thor's Hammer (World's HEAVIEST)
Assuming a proportional relationship between grip strength and what the average male American can lift, back-of-the-envelope math suggests Thanos could heft 120 million pounds, 10 million pounds more than the weight of the Titanic.
The hammer Stormbreaker is very similar to Mjolnir, made of mystic Uru metal and is nearly indestructible.
Superhuman Strength: Thor possesses class 100 strength and is easily capable of lifting 100 tons. Superhuman Durability: While in the form of an Asgardian Goddess, Thor possesses virtual invulnerability and immunity to all known Earthly diseases and infections.
In terms of the power to lift and move large objects, Superman has a stronger edge against Thor. Thor may have been able to move objects that weigh as much as planets, but the Silver Age Superman not only pushed actual planets out of orbit all the time, but even went so far as to move entire galaxies on a whim.
According to his official Marvel page, Spider-Man is capable of lifting up to ten tons, and that means that he is a lot stronger than some of the other characters that have peak-human strength. However, Spider-Man's strength pales in comparison to the likes of Thor and the Hulk.
How much can Thor lift? Thor can lift well over 100 tons with no difficulty, he is in the so-called Class-100 strength category. This means he is in the same strength category as the Hulk, but we have seen in Thor: Ragnarok that Thor can catapult the Hulk to the other side of the room with ease.
Great Power. Like his namesake, Spider-Man's strength and agility stand far above those of the average human, allowing him to lift nearly ten tons and to leap and move at incredible speeds with high accuracy.
In fact, the comics have put Superman's strength at a point where he's able to lift around 2 billion tons! To put that into perspective, the Empire State Building is only 365,000 tons!
In the stories (and the Marvel movies), we see the god throwing the short-handled hammer at his enemies. The top of the Mjölnir often (but not always) comes to a slight point, giving the overall object a somewhat diamond shaped appearance. This shape is similar to an inverted Tyr rune.
Mjolnir was forged by a dwarf named Sindri. While he was creating it, Loki, the trickster fire god, disguised himself as a fly and attempted to interfere with Sindri's work by buzzing around him. As a result, Mjolnir's handle was unusually short.
Other than Thor and Odin, certain other individuals have proven worthy of lifting Mjolnir in the primary continuity: Roger "Red" Norvell (a deliberate ruse by Odin) Beta Ray Bill. Buri (also known as Tiwaz, Thor's great-grandfather)
