What to read after Defending the Earth?

Earth is bombarded every day by objects from space. Most of the time they're harmless. But occasionally much larger objects come along that pose a real threat. If a large asteroid or comet hit Earth, it could change life as we know it. Is there a way to stop these threats before it's too late? In this nonfiction graphic novel, Max Axiom and the Society of Super Scientists go on a fact-finding mission to learn about Near-Earth Objects and discover methods that scientists are developing to defend our planet.
