A Ring System of our Own:

When the moon was formed after a collision between Earth and another a celestial body, it should have left lot of debris around Earth. The debris within the Roche"s limit *should* have formed rings around Earth.

In truth, it"s quite likely that Earth *did* have a ring (or a system of rings) sometime in the VERY distant past; however, any such rings would have only been possible for a short period of time after the collision between Earth and Theia (the hypothetical planet that struck Earth to form our moon). Unlike the rings that belong to Saturn, Earth"s rings would have dissipated pretty quickly.

Find out why, and learn what our planet would be like with rings at:
