Unveiling the Oort Cloud

Today we are doing a deep dive into the mysteries of the Oort Cloud, a distant and hypothetical cloud of comets that envelops our solar system. This spherical region stretches from about 2000 AU to 100,000 AU from the Sun, marking the outermost edge where the Sun's gravitational influence dominates. It's a thrilling tale of dynamics and how the solar system interacts with the galaxy!

No-one has ever proved that the Oort Cloud really exists. We just know that it Oort to be there.

Nudged by the YouTube algorithm to the vicinity of the Nora system, I was trapped in her orbit (subscribed).

I just love smart people that can give you a Youtube presentation without background noise and very clear speaking. Thanks so much.

[alexanderalza]

You had me at "a cloud of oorts" 😆

[paaabl.]

This channel is so underrated, I am guessing it is going to skyrocket soon

[brycefelperin]

I really love enthusiastic YouTubers. Enthusiastic, smart and scientific YouTube channels are the best. Subscribed!

Great video!! Even though I have a degree in Physics and have been a long-time astronomy enthusiast, I've never heard such a clear explanation of the Oort cloud, and the celestial mechanics methodology used to determine its properties.. and be delivered with such joy. Very well done! Thanks, Nora! You earned my subscription.

I've been into astronomy since I was a child, so 30 yrs +. Love this video I could listen to you explain space all day.

This is fascinating and delightful! 
It reminds me of an Advanced Topics in Astronomy class I took during my second year in college. It was taught by the head of the department and his enthusiasm was contagious.
As with this video, there was no math requirement, but he occasionally would put it up on the board just to show that it works. We only dealt with stars, not "rocks" as he called them. We got so much history and cutting-edge theories, I felt that he gave me my religion. I still have tapes of some of his lectures.

Thanks! I'll be back!

Big planets kicking rocks around. Neat description.

I’m glad that I found your channel. My 14 year old daughter has always loved science specifically math, physics, and astronomy. When she started her freshman year in high school back in a august 2023, she met with her counselor and informed her that she wanted to go to Caltech and study physics and astronomy. Her counselor told her that only boys go into the field and she should reconsider. This devastated her. So, since then I have been looking to find channel or females in science for her to watch and realize she can always do what ever she wants regardless what others think. We have subscribed and eagerly looking forward to see all your videos.

By the end of the video, I can say that it's a win-win experience. Nora gets to nerd out. And I get my vague knowledge of the Oort cloud brought into focus by her detailed explanation of the entire process.
Many thanx. *subscribe*

[JayTeeNIN]

Your videos are very organized and you are a very prepared person. I had to subscribe. Thank you for your hard work and your passion for the cosmos.

[XKathXgames]

This was great! Can't believe I hadn't found your channel before. Subscribed now!

[timmccaffery]

Always love your shorts. Deeper dive is very worthy for the Oort bodies! I'm more of a statics guy so very humbled by someone who digs the uber complicated dynamics field! LLaP

[RodneySandwhichez]

This was absolutely fantastic. I had to stop several times and look some things up. Great material and what a deep dive on this.

[matthiasmartin]

Thanks for sharing your knowledge with us!

[welingkartr]

Nice! I wondered about the Oort cloud and saw an article about a recent paper where they simulated motion of stars in the neighbourhood coming close every 70K years or so and causing changes in the inner solar system. Your description was quite helpful, though I could figure that there's some uncertainty given so many factors that influence this dynamic system. Thank you.

What an amazing surprise treat of a video! 👌
Super fascinating content! A definite subscribe. ✌️🖖

Excellent synopsis of current hypothesis and theory of the Oort Cloud! I find this one of the most interesting areas of the Solar system. With GAIA data it seems even more interesting, considering astrometry suggesting a near pass by Scholz’s star a mere 70k ya and a possible near pass by GJ 710 in a mere ( 😉) 1.5m years from now. Great
