SEJARAH PENEMUAN DAN KEDEKATANNYA DENGAN KITA
Collision of a big asteroid or comet could be fatal,
the immediate devastation caused by the explosion
being only one of the consequences.
The collision would eject a lot of dust to the atmosphere
cooling the climate for several years.
The mass extinction 65 million years ago
seems to have been caused by such an event.
As the comet Shoemaker-Levy hitting Jupiter in 1994 showed,
such collisions are still possible.
