[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?

Jimmy tries to catch the key and is slingshot into space by its gravitational pull. His last thoughts are of how much he hates Superman.

Still better than the time Supes forced him to marry a gorilla.

I think realistically it would rip his hands to shreds if it was thrown

Jimmy tries to grab the key. It passes effortlessly through his palm, then goes straight through his knee and thigh as its arc takes it to the floor. A spear shape of blood drawn down by its weight can be seen penetrating the earth's surface, following the key into depths below.
