Pluto, Comets, Asteroids, and the Kuiper Belt

We've just wrapped up a survey of all the planets and moons in the solar system. But is that all there is? Not even close! There are tons of objects that make up the asteroid belt, the Kuiper belt, the Oort cloud, you can't even believe how much other stuff there is! Let's check out all these things now.

Check out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!

I love how this was explained in a way that made sense. What an incredible and intricate solar system we have,

[mjm]

Nicely done. I was looking for a simple, clear, solar system video for children and this was one of the best. I even learned a few new things from it such as the Trojan asteroids.

Totally loved this video! You have an incredible gift of explaining complex concepts in understandable ways. However, what really amazes me is your ability to grasp a very wide range of technical subjects.

"Dwarf planet" when science attacks your insecurities.

Does the Ort Cloud interact with the “ort clouds” of other nearby stars?

I am so glad to see people like yourself, Dave, making videos to help educate people with accurate information!

In this age of limitless information, there's certainly no shortage of false information being pushed around by people such as charlatans and conspiracy theorist!

We need as much accurate information to be readily available and easy to access as possible! So, please Dave, keep making these great educational videos for those who really need them!👍

Totally just subscribed...Science well explained and digestible enough for the non science brain😂.... Awesome! 👍🏾

Your videos are like perfection, thank you very much for the education

Hey professor dave,
I just want a little explanation. You said, due to Jupiter's strong gravity it prevents asteroids recollecting to form a planet. In that case, sun which is much more massive than jupiter, should have prevented terrestrial planets (especially Mercury) from forming in its early stages.. Why it didn't happen? Also, how did Mercury being so small is staying intact beside such a massive object. I'm no expert in astronomy, just a curious mind 😅.

Thank you.

I love how Jupiter is like the protective older brother, his gravity and mass absorb asteroids that would otherwise hit earth

[christianhanscabornida]

thank you prof.dave... Really good presentation!

8:06 This is not a picture from a meteor shower. These are streaks from the normal night sky caused by a long exposure.

[neub]

Again, great explanation tying topics together, including why there is the asteroid belt. Now I know meteor and meteorite definitions in a way I'll remember.

Love your videos Professor Dave! Especially your intro... 😀

[pukhrajmansion]

You are great personality of world astronomy
Good presentation
Good subject matter
You are working for humanity

[ireneliteratus]

Asteroid belt: Who are you?
Kuiper Belt: I'm you but BIGGER
The Ort Cloud: Aww, The kids are fighting again

[cell.academynanolive]

Still sad about Pluto :( great video professor!!

[Jr_Scientist]

Since the Kuiper Belt was founded in 1992, Pluto's designation as a planet fell into jeopardy.

[RobinTheJester]

wouldn't the existence of the trojan asteroids (technically) mean that Jupiter doesn't fit the definition of a planet described in the episode, since it doesn't clear it's orbit?

So glad this was in my recommendation well explained thank you ✨👍🏻
