What's Left on the Moon?

There's tons of robotic equipment from all different probes and just a lot of other equipment. It's hard to say exactly how much stuff has been left on the moon, but NASA has estimated that it's about 400,000 pounds or 181,000 kilograms according to Earth gravity. So we have moon visitors and what they've left, you're in collection kits on the moon and there's a gold olive branch. Full or empty,. That's a toll, right?
