to move a moon-sized body from Earth's orbit? Background, I've been curious about science my whole life, but I've normally focused on paleontology as I loved dinosaurs growing up. I'm interested in physics but don't know enough regarding forces like gravity or physical forces to calculate things like this. Basically I'm a nerd and a project I'm working on is quantifying in-universe feats of fictional characters, in this case Megatron from the 1980's Transformers. I know it's stupid and might not be the best application of a physics forum but I'm not sure where to look as I'm aware of my limitations regarding computations. I can memorize history and literature instantly but equations have never been a strong point. Basically though, I'm looking to learn how powerful an explosion would need to be to move a moon-sized planetoid (Cybertron), composed of the strongest metal in the galaxy and with roughly the same gravity as Earth's, clearly out of Earth's orbit. This is mainly for me to calculate how durable said character was while being at ground zero of such an explosion and tanking it. Again, I know it's ridiculous, but you'd be surprised how much I enjoy cataloging fictional feats and cross-referencing such things in fanboy Deadliest Warrior-style discussions. Sorry for being out of line on here if that's the case. I appreciate any and all help given.
