Who else believes the possibility the asteroid belt to have actually been a planet at some point in the past?

I have already researched this, and come up with a few different answers. I firmly believe at one point in the past the asteroid belt between Mars and Jupiter had actually been a planet of possibly 'Earth-like' proportions in virtually all manners...atmosphere, life, etc. I am open to all arguments for and against this idea.|||Bode's Law or Titius-Bode law


The first link tells you everything.





Briefly:


The semi-major axis, 'a', of each planet outward from the sun in units such that the Earth's semi-major axis = 10, with





a = n + 4





where n = 0, 3, 6, 12, 24, 48 ..., with each value of n %26gt; 3 twice the previous value; the resulting values can be divided by 10 to convert them into astronomical units (AU). For the outer planets, each planet is 'predicted' to be roughly twice as far away from the Sun as the next inner object.





n n+4 s.m.axis planet


0 4 4/10 Mercury


3 7 7/10 Venus


6 10 10/10 Earth


12 16 16/10 Asteroid belt


24 28 28/10 Mars


48 52 52/10 Jupiter


96 100 100/10 Uranus





This law lends credence to the asteroid belt being originally a planet that later broke up.


Adding all the mass of all the asteroids is less than the moon.


(see second link).


However our moon is pretty big, and who knows how much dust was blown out of the solar system by solar wind when th asteroid/planet broke up?


And how much mass can't be detected and added to the total?





Mercury: 0.33 x 10^24 kg


Venus: 4.87 x 10^24 kg


Earth: 5.98 x 10^24 kg


Moon 7.36 x 10^22 kg


Mars: 0.65 x 10^24 kg


Jupiter: 1900 x 10^24 kg


Saturn: 570 x 10^24 kg


Uranus 87 x 10^24 kg


Neptune: 100 x 10^24 kg


Pluto: 0.7 x 10^24 kg


(see fourth link)





Let's say is it was a very small planet the size of out moon.


The tremendous gravity of Jupiter (next to it) would have caused huge tidal affects on the little planet that eventually broke it up. Then the remains would spread out making a ring of asteroids.








I think the asteroids could have been a planet at one time.





P.S.


Jupiter's Great Red Spot is only a storm that has lasted 400 years.


It couldn't have been formed from the asteroid/planet breaking up.


(see third link).|||I dont think so- my reason and my opinion- the belt is huge, i repeat HUGE in porportion





the diameter of the thing is more than just a few million miles long, most of the rocks are miles in diameter themselves, to the math with an average diameter of 1 mile across, the belt, lets say 3 miles at the thiniest (im prety sure much wider though)





thats a rough estimate of several moon sized planets combined- meaning a very very small planet if any





that kills size





as for being a planet, i high doubt it, the space rocks are very evenly spaced, only planet wise explaination is that the planet broke appart as it traveled around the sun- which is next to impossible to happen- if what you say is true, the mass of planet would produce enough gravity to hold itself together if it was falling apart so theres noway it was once one whole planet





as for life and other stuff on the planet, those rocks dont contain much of each kind of element- what makes earth capable of life is that this here planet has a large percentage of varities of elemnts as compared to other planets|||There isn't enough total mass in the asteroid belt to make a decent sized planet. Nothing on the order of the size of the earth. This, along with the disruptive effect of Jupiter's gravity, are the two main reasons why the asteroid belt most likely never formed a planet in the first place.|||We are subjects of the 'lost planet' you speak of...we arrived here 65 mln yrs ago when we super-nova'd and have not looked back since. Freaky huh? But true!|||The mass of everything in the asteroid belt -- everything -- amounts to about 0.05% the mass of the Earth. A third of that is in the largest asteroid Ceres. The Titas-Bode rule predicts a planet should be between Mars and Jupiter, and Ceres' orbit lands neatly within that formula. But it looks like there was not enough matter in that region of the solar system to pull itself together into a single planet.|||Asteroids are left over materials from the formation of the Solar System. These materials were never incorporated into a planet, because of their proximity to Jupiter's strong gravity.|||Planets are mainly formed when the inter-stellar dust and gas revovlving round a parent star ( or not even a star) condense and supercool to form huge chunks of matter called planetesimals.





The planetesimals combine with the other due to gravity and form a large celestial body.





If the gravity is enough, the body can achieve hydrostatic equilibrium and pull itself into a sphere.





But at the time of formation, the planetesimals near the gravitation of Jupiter could convert into a planet as the Jupiter' gravity made the rocks to collide with each other rather than to combine.





Hence they remain between Mars and Jupiter orbiting the Sun.|||Nothing is impossible along those lines but everything I have read on the subject says the asteroids failed to form a planet.
