Lagrange points Definition and 18 Threads

Hello. I've been reading about the Lagrange points... https://en.wikipedia.org/wiki/Lagrange_point ...and also about Pluto and its moons. Having discovered that the barycentre of the Pluto - Charon system lies at a point in space between the dwarf planet and its major moon Charon a number of...

If we fabricate a surface like this... (source:www.youtube.com/watch?v=7PHvDj4TDfM) ... and rotate it around the appropriate vertical axis at the appropriate speed, would it be possible to get a bead to roll in an "orbit" around L4 or L5. (a) Possible at all in principle? (b) Practical...

If all the Lagrange Points(L1, L2, L3 and L4) are utilized to depart telescopes like JWST, Luvoir and Habex then is it possible to have a Telescope aperture with a half size of Solar System?

Hello. With the recent interest in the JWST orbiting at the L2 Lagrange point of the Earth - Moon system, I was wondering about the dynamics of the Pluto - Charon system. Specifically, the barycentre of that system. This barycentre lies at a point in space between these two bodies. Does...

What is the delta-v requirements from each of the Earth-Moon lagrange points to landing on the lunar surface? What would be the best software I could use to visualise and calculate that kind of thing? Thanks.

Hi Does anyone know what the straight line distances of L4 and L5 are from Earth? Many thanks.

Two questions about Lagrange points. (1) According to Wikipedia, "libration is a perceived oscillating motion of orbiting bodies relative to each other," whereas the Lagrange points are, with respect to two bodies, null points for a (real or hypothetical) third body with respect to the sum...

I'm trying to find out if Mars has any Lagrange Points - L1 and L2 specifically. A lengthy trawl through Google's webpages suggest that they may exist, although if so they would be extremely close to Mars, being gravitationally bound by Phobos and Deimos. Is this true? PS. Should Mars indeed...

The Wiki article shows 5 Lagrange points. I can “see” how the points L1, L4 and L5 points would be balanced by the gravitation of the two bodies, but not the L2 and L3. For L2 and L3, it looks to me like the combination of the Sun’s and Earth’s gravity increase pull and make less stable. So...

Hello everyone! I'm currently trying to plot the effective potential for Sun-Jupiter system, to show the lagrangian points in this system. I've converted to a system of units where G=1, m_sun+m_jupiter=1 and R=1, whereby I get the following equation describing the effective potential of a third...

(Sorry text is hard to read, please see attached document for an easier read) I am having trouble with #6, I'm not sure if what I have going on is entirely correct. Also #7 is a little confusing. Problem Statement & work done: For an object in orbit around a second, there are five LaGrange...

Hello everyone! I just finishexd reading Death By Black Hole and I was interested in the Lagrange points. Neil talks about how if you placed objects inside of them you could use the points as place holders for objects while building in space. I couldn't seem to find anything about the width of...

Physics gurus: I understood from Newton's Law that a 2 bodies would rotate around their common center of mass. Should one body disappear (Harry Potter invoked here), the other would go flying off at a tangent... like a 'David's Sling" releasing a missile. The mass of the bodies was crucial to...

So, I'm working through some ideas dealing with Lagrange points. I understand that, the rotation and mass of 2 objects in space create stable areas where an object of "insignificant Mass" compared to the objects it's balancing against, allows for the placement of an object in a stable area...

I'm trying to figure out how much force, over what period of time, is necessary to reach an earth-moon Lagrange point. L1 is about 323110 kilometers from earth, and an object there could remain (more or less) stationary relative to the Earth and the moon. Earth gravity is working against the...

Hey a friend asked me for help on his physics homework, and I found this place and was wondering if you guys could help me out. 2: In 1772, the famed Italian-French mathematician Joseph Louis Lagrange was working on the infamous three-body problem when he discovered an intersting quirk in the...

1: Determine the escape speed of a rocket on the far side of Ganymede, the largest of Jupiter's moons. The radius of Ganymede is 2.64 X 10^6m, and its mass is 1.495 X 10^23 kg. The mass of Jupiter is 1.90 x 10^27 kg, and the distance between Jupiter and Ganymede is 1.071 X 10^9m. Be sure to...

A)How many LaGrange points does the Earth/Moon system have? B) How many are stable (no stationkeeping neccessary)? C) Roughly where are the stable points located? 1/2 point point for each answered correctly
