Explore outer space through interactive augmented reality experiences!Did you know that a 220-million-pound (100 million kg) asteroid flattened millions of trees in Russia in 1908? Or that there may be more than one trillion comets in the solar system? Most comets and asteroids travel through space far from Earth, but when the planet crosses paths with an asteroid, the results can be beautiful, destructive, and long-lasting. Comets and asteroids don't experience erosion, so they can remain nearly unchanged for millions of years. Scientists study these objects to learn about the early solar system. Modern technology has allowed humans to find out more about asteroids and comets than ever before and even land probes on comets that are hurtling through space. Join scientists on a journey from the asteroid belt near Mars to the distant Oort Cloud in pursuit of comets and asteroids.
