Why Isn't the Asteroid Belt a Planet?

It seems like there's a strange gap in between Mars and Jupiter filled with rocky rubble. Why didn't the asteroid belt form into a planet, like the rest of the Solar System?

0:52 LOL.   Interesting stuff, keep the interesting tidbits coming!

I like Ceres because the way belters speak sounds cool. And because Drummer (Cara Gee) is ridiculously hot!

Dawn is my favorite object in the asteroid belt :-)

I have been wondering this. Thanks for clearing it up.

Thank you for taking the time to record this information.

A few years ago in Geology class, they taught us the destroyed planet hypothesis, but I already knew this was not the most likely explanation, and Jupiter's gravity would prevent a planet forming in the first place. So when the question came up in the exam, I wrote what they had told us, then explained why it was wrong.

As an avid Sci-Fi fan, there's really only one choice for me: 4923 Clarke

No need for me to subscribe or join Patreon.  I have now seen enough of the background to triangulate the location where these videos are shot and I watch them all *live*, (including behind the scenes material).

Notice my car in the background?

My favorite object in the asteroid belt is that one rock that orbits around the planet.

My favorite ABO?  Russell's Teapot... which *definitely* exists.

Axis. Axis is my favorite object in the asteroid belt

This guy's head bounces around like he's a bobble-head doll.

My favorite object in the asteroid belt is a tea pot :D

It's fun to watch older videos to see how they have evolved. Abandon jump cuts to save filming & editing time? Decide it wasn't adding enough to the video?

what if the asteroid belt was originally part of mars's formation system but some how was cut off like solar wind pushing some of the material from mars's formation to it's current location where random clumps formed or the gas giants gravity pulling and nudging the material from mars(and if I’m wrong if the mass of the asteroid belt was added to Mars during formation it would have higher gravity, possibly thicker atmosphere, maybe even a functional magneto sphere)

Nasa's Dawn mission will be arriving at Ceres very soon. I can't wait to see some detailed images and learn more about the dwarf planet's composition. If I remember correctly, Dawn will begin to orbit Ceres this April.

aahh thank you for answering a late night question, brought up by a late night youtube video voyage!

[Beanmachine]

0:10 your talking about planetessimals! the materials that form planets

[kturob]

Can our solar system or sun make any more planets

I think a planet would be stable in orbit at about 4AU as long as it wasn't in a kirkward gap. One day in the far future there will be.
