How Mighty Jupiter Could Have Changed Earth's Habitability


www.astrobio.net said:

Is Jupiter a friendly planet, Earth's enemy, or perhaps both? For decades, scientists have talked about how the giant gas planet keeps some asteroids from striking our small world, while others have pointed out that Jupiter's gravity could send some civilization-shattering asteroids our way.

While that debate goes on, a subtler question arises about how influential Jupiter was in the early Solar System. Jupiter is by far the heavyweight planet in the Solar System, weighing in at 320 Earth masses. Its gravity not only influences small asteroids that go by, but also tugs on other planets in the solar system – including our own.

Well so far, Jupiter has protected us more than not protecting us, which is a very good track record. However, I'm sure we all realise that at some point the track record will be broken.

Until then, relish in being alive!

"From time to time there appear on the face of the earth men of rare and consummate excellence, who dazzle us by their virtue, and whose outstanding qualities shed a stupendous light. Like those extraordinary stars of whose origins we are ignorant, and of whose fate, once they have vanished, we know even less, such men have neither forebears nor descendants: they are the whole of their race."  -- Jean de la Bruyere 1645-1696.
