same, i was also wondering why the L2 would be "stable" when all the forces are on one side, but of course they'll need the acceleration to stay in a circular motion
I understood the L2 for JWST but what i dont understand is it's orbit around the moon... Or what i have seen on other simulations is that it's orbit is far away from the moon's center of gravity... So where is it free falling to for maintaining it's orbit around the moon... Or does JWST has orbit around moon???
@@user-bx6vw7oh8s the JWST orbits around the Sun; it is in the L2 point for the Earth and Sun, not Earth and Moon. This is so that the Earth is always between the JWST and the Sun, keeping most of the IR 'noise' from the Sun from interfering with the JWST's sensors.

A fun thing with Lagrange points is that they form the basis of extremely efficient orbital trajectories called "weak stability boundary transfer trajectories", part of a category of "low-energy transfers". Together, the system which connects these trajectories is called the "interplanetary transport network". If you have enough time and patience, you can use use these trajectories to wander around the Solar System for little to no fuel. Sometimes there is a free lunch after all!
This was verified by the right reverend Billy F. Gibbons when he described the point like this: Rumour spreadin' 'round In that Texas town About that shack outside La Grange And you know what I'm talkin' about Reverend Gibbons assumed this was common knowledge at the time.
Great video, but I wish you had explained how the Coriolis effect works at L4 and L5. I understand the effect as it applies to weather, but the extension to objects orbiting in space was not obvious.
I couldn't have made Lagrange Points more Confusing and Complicated myself ... Well Done ! ..... Now I can search for a clearer more simpler explanation ... Tanks a Lot !
This video does a great job of explaining the concept of Lagrange Points. The explanation is about as clear as could be. Maybe there should be some mention that the James Webb Space Telescope is heading for L2.
@@chrisrus1965 If there are rocks, they are more likely to be at the "stable" points ; 4 & 5. Rocks usually don't have means of propulsion for coerce corrections ;).
Bro it’s awesome to see your channel expanding. You put out high quality content, and I always learn more than I can handle for a day with just one video! Love your stuff man, keep it up!!!
as always Nick a perfectly simple to follow explanation, i very nearly gave this vid a miss (yes im a little crazy), but you once again taught me something that I Thought i already knew !
I have been searching for why L4 and L5 exist for so long! Thank you for at least offering SOME kind of explanation. "We're not really sure why they even exist" will do for now! At least it's an answer. Thanks!
@@ScienceAsylum And Scott Manley just did an interesting piece on it where his computer sim shows the asteroids caught in Jupiter's L4 and L5. th-cam.com/video/7PHvDj4TDfM/w-d-xo.html 9:31 It could just be a motion plugged into the computer software, but it looks like they are all rotating around the axis of the motion of the planet.

That was really well done and very clear. You make this stuff so much fun. (By the way ... what's the, uh, Lagrange situation around Milton's home? How many suns, moons, etc.? And what do they call those points where he's from?)
Great video! Could you do a video on orbital resonances next? Also, can you explain more about trojan asteroids, especially those in the Lagrange points (L4 and L5) of Jupiter? I personally find these quite fascinating, and the fact that a spacecraft ( _Lucy_ ) will be launched in 2021 to explore Jupiter's trojans really fuels. By the way, keep it up with your content!
This is amazingly good description of what LaGrange points are. Very understandable. The next phase of NASA could be placing some people in orbit around the LaGrangian points. This was discussed in a press conference as a possibility. This would be the first example of a manned spaceship outside of "earth low orbit." How to get people excited about it? Videos like this! Thank you...
’Bout time You got a sponsor! I bet they really came to shave the day? Your videos are really great, and today I learned something completely new. Never even heard of these points before.
Thanks for a very good video! :) Although it seems to confuse many people, it's important to hammer home the fact that acceleration does NOT mean "Go FASTER grandma!!" To scientists (& to us regular people who are just scientifically-minded!!), 'acceleration' means 'a change in speed.' Thank you for pointing that out - most people don't realize it. So, folks... acceleration (that 'change in speed') can be positive ("Go FASTER grandma!!"), negative ("Slow DOWN, grandma!!") or zero ("Nice cruise-control, grandma!!") If you're ever in a situation where you're riding in a car & a scientist is driving - & you see something they need to avoid by going faster, NEVER say, "Hurry - ACCELERATE!!!" That scientist will say, "positively or negatively." Just say, "Go FASTER!!!" ;) tavi.
I understand WHAT Lagrange points are, can we have a video on how they work in more detail? I'm most interested in L4-L5 points. How do they center back?
Lagrange points are cool and very important. I learned about their significance after reading an article about the proposed James Webb Space Telescope will be placed at L2 (L1 is not preferred due to the Sun's intense glare).
This is the best explanation I was able to find on TH-cam.In fact, I forgot the fact that net force between Earth and Sun should be positive to provide centripetal force, till you wrote the Newton’s second law equation. But why does Aditya L1 space craft need a circular orbit around L1? Why can it not be in a simple circular orbit around Sun , like earth does?
Dude you are so awesome but still so less followers. This is soo bad. But your videos are awesome. Whenever I struggle to understand a topic this is the place I come . Thank you soo much mahn. Lots of love from 🇮🇳
The more eccentric the orbit, the less stable the points are. At sufficiently high eccentricity, the Lagrange points are still _technically_ there, but they become less useful.

Would this make those La Grange points around Jupiter a great place to go asteroid mining ?
It's actually not free, the orbits of the hosts pay for it.

I thought I fully understood Lagrange points..Turns out I was wrong! Great explanation!
Yup. Me too. The coordinate stuff threw my brain for a loop.
Threw your brain for a loop !, funny but does that mean your brain has Lagrange points too ?
For some reason, TH-cam think that I need to know about Lagrange points. I’ll trust that your video will be the best explanation of all of them.
The James Webb Space Telescope is a really popular topic right now.
In the last millennium, there was a La Grange point somewhere around the 1970's. It was on the Top of the ZZ coordinates.
Ha! Or should I say "Aha ha ha how!"
Heaven, Hell or Newton
This was verified by the right reverend Billy F. Gibbons when he described the point like this:
Rumour spreadin' 'round
In that Texas town
About that shack outside La Grange
And you know what I'm talkin' about
Reverend Gibbons assumed this was common knowledge at the time.
At that point, a guitar will spin around freely at constant speed.
Thanx, this was the comment I was looking for.

I have an interview working with the JWST tomorrow and this was very helpful to understand the different Lagrange points and why L2 is used.
Glad I could help. Good luck with the interview!
I am here a couple days after James Webb launched! Perfect timing! 😀

I have watched 7 videos on Lagrange points today and this one made the most sense. Thanks!
Glad it helped! 🤓
I just saw your Lagrange mechanics video, and thought "cool now how about the L points for a follow up", and wow here it is.
This video does a great job of explaining the concept of Lagrange Points. The explanation is about as clear as could be. Maybe there should be some mention that the James Webb Space Telescope is heading for L2.
Wait: Are there lots of rocks at L2? Is Jim in danger there?
We know Jim can see far. Can it also see near enough to step out if the way of L2 rocks?
@@chrisrus1965 If there are rocks, they are more likely to be at the "stable" points ; 4 & 5. Rocks usually don't have means of propulsion for coerce corrections ;).
You have improved so much in terms of script and graphics. The topic chosen was interesting as well. Keep it up man!

Well it's not a surprise anymore that we'll always be amazed by the teaching skills of this man.
Thanks for helping me understand Lagrange points. I had a very small idea of them. Now I know more.
Glad I could help! 🤓
The mountain analogy really helped
That's great! Thanks for letting me know.
Finally a clear explanation on Lagrange points, you sir deserve all the cookies.
Could you do more episodes on astrodynamics/orbital mechanics?
I like to do them every once in a while. There will be more.
I'm here 2 years after this was released cause it's SO relevant right now, lol! Thanks for the explainer!

This video is one of my favorite now. I loved the concept( which I never heard). Great video Nick. Keep it up!👍
Glad you liked it.
Thanks for this explanation. L points hardly ever get mentioned and I wondered about their usages.

Nailed it
How about a new conspiracy theory where the government might be hiding or denying the existence of an L6 point? ;_)
Lol
You're getting stuck in Godel's incompleteness theorem
This video just got recommended to me in perfect time!
Now I understand where the James Webb is going to be placed. So it's semi stable that would mean course correction from time to time. Great video.
Yep! It has little jets on it so that it can periodically correct itself.
Extremely cool. Pretty crazy that such things exist.
As always, an excellent, intuitive, entertaining, and most importantly educational video. Thank you so much for making these. Your videos make my day.
Finally, you got sponsorship.
Love you're videos.
I *semi*-understand your videos now since I've been taking physics for almost 4 months now.

Yep! That's especially true for L4 and L5 because they're the most stable of the 5 points. This is a big reason we don't use them.
