Visualization of the Sun-Earth Lagrange points. Orbital mechanics is a fun subject, as it involves a lot of seemingly empty space that’s nevertheless full of very real forces, all of which must be ...

Lagrange points are locations around a two-body system where the gravitational forces of the two objects, in this case Earth and the Moon, are equal to the centrifugal force. This allows for a ...

Correction: An earlier version of this story erroneously stated that China’s Queqiao satellite was orbiting the Earth-Sun L2 Lagrange point. In fact, Queqiao orbits the Earth-Moon L2 Lagrange point, a ...

The James Webb Space Telescope has been traveling through space since its launch on December 25, 2021, and will soon face the next crucial step in its mission, performing an orbital burn to insert ...

"In RTBP systems, Lagrange points between the two celestial bodies provide specific locations around which a spacecraft can orbit," explains Mingpei Lin, a member of an AIMR research team. "The ...
