i have a question about the creation of planets.?

Question

if planets are created bc of clumps of astroids gain gravety and suck more astroids in then y isnt there a planet in the astroid belt?

Answer 1

This belt is affected more by the gravity of Jupiter than by other asteroids in that belt. So you can say there isn't just enough gravity for them to coalesce.

There is an old theory that this belt is a result of a planet destroyed due to a collision, but the modern theory suggests that its the leftover rocky matter that couldn't form a planet.

Besides, the combined mass of all asteroids in that belt is estimated to be 1/1000 th of Earth's mass. So even if they ever coalesced, the resultant body would be about 1300 - 1500 km (810 - 930 miles) across, which is less than one third to one half the diameter of moon, and wouldn't really qualify to be a planet.

Answer 2

The astroid belt is theorized to be a planet that broke up because of the gravitational effects of Jupiter. Once everything settled down and started properly orbiting the sun, the collisions of the various aggregations of rock died down. For example, we know that the cratering of the Moon occurred a long time ago, there are very few impacts nowadays. So, things aren't moving as randomly anymore as they did when the sun was in its infant stages. The planet forming has long since stopped. We ended up with 9 planets (maybe more beyond Pluto but who cares). The sun sort of "cleaned house" at some point by releasing a burst of energy (the t-Tauri wind), sweeping the clutter out beyond Pluto. All that leftover debris is now out there, called the "Oort Cloud" after the astronomer that discovered it. That's where comets come from. But as far as new planets go, our solar system is way past the era of planet formation.

Answer 3

No, asteroid belt is different because it's made of rocks and crystals which had not combine together to create a planet that it doesn't have a core of gravity. It's a debris of solar system's formation, and it has been suggested before that it used to be a planet but it has been destroy by a major collision, never successfully turn into a planet and turn into debris which called asteroid belt.

Answer 4

The short answer is that Jupiter's gravity has prevented the asteroid belt from coalescing into a planet. The popular theory now is that the asteroid belt is simply material leftover from the formation of the solar system that was sort of "herded" into place by Jupiter. It is not believed to be the remains of a destroyed planet.

Answer 5

there's a theory that the asteroid belt used to be a planet, but was destroyed by a collision with a large comet or meteor.

Answer 6

Maybe none of them have enough gravity...

Answer 7

You need to go and check ...it was there when I visited.

Answer 8

It could be that it's still forming...

Answer 9

bcuz i stole it last nite...
