(6,310 posts)The moon absolutely cannot be knocked out of orbit minus some enormous object hitting it, like another planet. In that case, earth probably wouldn't fare too well either. You would need an object about the size of a dwarf planet or planet.
Nuclear reactors don't explode like a nuclear bomb when they melt down. Typical "explosions" like Chernobyl are from another source, like hydrogen. Instead, nuclear rods begin to "melt down" because they get too hot, meaning that radioactive material can be vaporized into the air or leak into the environment.
Nuclear rods are immersed in water. Nuclear rods are extremely hot, which causes the water they're immersed in to boil. Steam is released, which spins turbines, which creates electricity.
Even if every country suddenly fired their entire nuclear arsenal at the moon all at once (assuming every warhead would hit and detonate), nothing would really happen (minus large blasts on the moon). To blow the moon up, you would need to drill into it (like in the movie Armageddon), and plant billions of nuclear warheads inside of it.
Let's say you were able to break the moon apart. Gravity would just take most of the particles and reform them into a sphere almost immediately.
Basically, tldr: The moon can't be destroyed by humans.
