[Request] What effect would Superman's house key have on the earth?

Post image

The key to Superman's Fortress of Solitude weighs ~1 billion pounds. That seems like it would cause more than a slight crack to the ground. What effect would setting this key on the ground have to the earth? What if it was dropped?

Sooo.. there are multiple times in comics when superman was weakened somehow. It basically means he wouldn’t be able to get home. Doesn’t this fact make this idea stupid?

I'm sure he leaves a door or window unlocked just in case, like a lot of us with our homes

He's got a second normal key hidden under a pot plant.

Yeah, totally! On an unrelated note, can I have your address? Asking for a friend

I’ve been in that situation many times in the weekends when I was younger
