Is there a ceiling for stable L4 or L5 masses?
L4 and L5, the Lagrange points 60 degrees leading and trailing an orbiting body, are famous for being stable.
A well known example is the Trojan asteroids at the Sun-Jupiter L4 and L5. Nodding to ...

Parking a telescope at a Lagrange point: is this a good idea from a debris point of view?
The James Webb space telescope is supposed to be located at the Earth-Sun L2 Lagrange point.
Do we expect the region around that point to have a higher concentration of space debris, asteroids, dust,...

Can the Gaia telescope detect small temporarily captured asteroids near its Lagrange orbit?
The Gaia space telescope is in a Lissajous orbit around the Sun-Earth Lagrange point 2. The orbit period is about 180 days and the size of the orbit is 263,000 x 707,000 x 370,000 km. It has been ...

Lagrange points and the radius of the Hill sphere
(Disclaimer: I know the "Hill sphere" is just an approximation of something which isn't genuinely spherical.)
In a two-body system, the approximate formula for the Hill sphere radius of the smaller ...
