It's an old question since Ceres and the other big asteroids were noticed. Some think that Mars may have been part of the missing planet system, a moon of a bigger planet.

"There's room for another planet between Mars and Jupiter," says Chambers. "Given that planets formed everywhere else, why couldn't another planet have formed there?"

Of course, we all know why...but I am not saying it!

Is this the modern version of the Snipe hunt?

Xenu did it...

Well, supposedly a Mars-sized body slammed into the early Earth and reformed the Earth with the Moon. So that's one place a Mars-sized planet could have gone. Of course it's also possible that there just wasn't enough material in that slot to clump together and form a planet.

We're going on a planet hunt.
We're going to find a big one.
I'm not afaid. Are you?

We're looking out to space.
It sure is high.
It sure is wide.

Well, there's nothing over there.
Nothing over there.
Nothing out there.

Hey! Wait! I think I see something!
Quick! Everybody run!

The Titus-Bode Law predicts a planet at 2.8 AU, which corresponds with the Asteroid Belt.

Hoagland has borrowed (ahem) TVF's idea.

It would be nice if TVF would drop Hoaxland's "Face on Mars" crap, but alas...

Here's the link to the most current revision to TVF's EPH:

I read or saw somewhere that the total mass of the asteroid belt was between the Moon and Mars; and that if a planetoid existed there once, that it was probably struck by a Ceres size asteroid and destroyed. Either way, there's enough raw materiel there to allow mankind to exist for thousands of years on Earth, Mars, our Moon and the moons of Jupiter, Saturn, Uranus, Neptune and Pluto.

So, be vewy, vewy, quiet!

[LibWhacker]

Recent simulations have suggested that the gas giants of our solar system formed with circular orbits but moved into their more elongated paths about 4 billion years ago...

And why exactly did THAT happen?

This is another older topic. Bode's Law is a mnemonic, at best.
