Could The Asteroid Belt Become A Planet ?
« on: 22/12/2009 13:20:00 »
Dearest Asteroid-Beltologists,

As a sheepy I of course luff the asteroid belt. It's my all time favourite bunch of rocks and things that reside between Mars and Jupiter.

Look here it is



Being Delivered Next Tuesday



Please do not confuse it though with a Haemorrhoid Belt thusly:


A Haemorrhoid Belt Earlier Today


As ewe know, planets are made when lots of rocks and stuff come together because of a magic force called gravity. Well, could that happen to the asteroid belt ?...and if not..why not ?..after all...it's made up from lots of big asteroids and small ones too..so surely the big ones attract the smaller ones yes ? and so on and so forth to make a new planet..yayyyyy !!

whajafink ?


hugs & shmishes


mwah mwah mwah !!



Neil
If I was travelling at speed in the belt asteroid
It's the rocky things that I'd want to avoid

No they cannot form a planet for two reasons.  Firstly,  there just isn't enough stuff in the asteroid belt to form a decent sized planet.  and Secondly because the asteroids are smallish and "next door" to the giant planet Jupiter.  The orbits are quite badly disturbed in the long term by Jupiter and this creates zones of avoidance that are close to resonance ratios and to coalesce into one planet asteroid would have to cross these zones of avoidance

Brillinat ...thank ewe very much Ian..

erhhmm....sorry to ask ewe this further but could ewe please explain what a ' zone of avoidance' is and what a ' resonance ratio ' is too ?

Thanking ewe muchly.

the period of the orbit of mars about two earth years  The period of the orbit of Jupiter is about twelve years.  Most of the asteroids have orbits in the range three to seven years  if an asteroid had an orbital period of say four or six years it would come close to Jupiter regularly and be disturbed by it.  This is precisely what is found  they are called the Kirkwood gaps in the asteroid belt.  similar gaps are also seen at ratios of  5:2 and 2:3 of Jupiter's period  these sorts of relationships are called resonances

A similar effect can be seen in the rings of Saturn  the big gap called the Cassini division corresponds to an orbital period resonance with the orbit of Saturn's biggest moon Titan
