Simple, all you have to do is shoot at them, and don't get hit. The building that's in the asteroid belt is in the middle, when you get on the planet touch the key. A funnel-like, black hole-looking warp thing will open up. Enter that and it will take you to where Mordred is.
On poptropica, when you get to the asteroid belt, if you are looking for Mordreds little castle that holds the key, go to: X 12 and Y 80. There you will find the little asteroid Mordred is hiding on.
TO get into the asteroid castle you have to complete the puzzle on the door.

The asteroid belt is in space.I think you'll find that the asteroid belt is a very dangerous place to fly a spacecraft through.In real life, crafts are sent over or under the asteroid belt, not straight through it like in films.
Go to the lower left, towards the asteroid belt, and look for an extra planet.
Find the giant asteroid they're talking about. Look in the asteroid belt in the lower left of the solar system.
