Well , I'm guessing this is for your homework considering I used it for mine haha , but the answer is Jupiter's Gravity .
Scientists theorize that a planet-sized object collided with earth to form the moon.

No planet has "disappeared" (at least not from our solar system). You are probably referring to Pluto. Pluto used to be considered a planet, but scientists have discussed this topic and now it is just considered an asteroid.
It is real, but it is an asteroid, not a planet.
The planet that is red is mars.why because scientists are smart enough to know there colors :)
scientists theorize that it was jupiters gravity that kept it from forming
Jupiter's gravity :D imma smart cookie (rawrr) ^.^
the only planet that scientists do not consider a planet is Pluto, (but they also found new planets in the asteroid belt.)Pluto
Scientists say that Pluto is not a planet because, like Ceres in the asteroid belt, it has failed to clear its neighborhood of planetesimals and other debris.

All the planets after the asteroid belt besides Pluto. (Which scientists proved that Pluto is not a planet.)
Saturn is outside the Asteroid Belt. It is an "outer planet".
No, its an inside planet because it,s inside the asteroid belt.
Currently the combined mass of all the asteroids in the asteroid belt is much less than that of any planet, though there were probably many more asteroids in the belt when the solar system was young. One of the leading hypotheses is that gravitational disturbances from Jupiter prevented a planet from forming where the asteroid belt is.

jupiter is an outside planet because it is located outsid the asteroid belt.
