Comets & Asteroids

Asteroids

Asteroids are small, airless rocky worlds revolving around the sun that are too small to be called planets. They are also known as planeloads or minor planets. In total, the mass of all the asteroids is less than that of Earth's moon. But despite their size, asteroids can be dangerous. Many have hit Earth in the past, and more will crash into our planet in the future. That's one reason scientists study asteroids and are eager to learn more about their numbers, orbits and physical characteristics. If an asteroid is headed our way, we want to know that.

To Our Guest

Our Guest will be able to see the comets and asteroids on November 28, 2014 at 6:44 a.m. They sky will be filled with comets and asteroids. Our Location will be in the European Space Agency/ NASA. There will be snacks for you to enjoy.

Comets

A comet is an icy body that releases gas or dust. They are often compared to dirty snowballs, though recent research has led some scientists to call them snowy dirtballs. Comets contain dust, ice, carbon dioxide, ammonia, methane and more. Some researchers think comets might have originally brought some of the water and organic molecules to Earth that now make up life here.
