Meteor is a dark red projectile in Earth Editor. It creates explosions when in comes into contact with any element while it is moving (excluding black hole and white hole). This projectile will make a crater in that element, while the other material formerly being in that crater gets pushed out, and is thrown from the gravity point until it flies back to the center of gravity.
In ver1.0, meteor was originally called fire, but was renamed to meteor in ver1.1. The more commonly known fire was implemented in ver1.6.
