Rethinking Jupiter
|
| Topic: Meteorites, Comets and Asteroids |
11/12/07 |
| The planet Jupiter is thought to act as a "cosmic vacuum cleaner," sucking up comets and asteroids that could potentially hit the Earth and endanger all life on our planet. But new research has more closely examined Jupiter's ability to protect the inner solar system, and there are some suprising findings. |
