"In #CelestialMechanics, the #LagrangePoints (/lə.ˈɡrɑːndʒ/; also #Lagrangian points or #Libration points) are points of equilibrium for small-mass objects under the gravitational influence of two #MassiveOrbitingBodies. Mathematically, this involves the solution of the #RestrictedThreeBodyProblem."

DYK our #Moon doesn’t just change phases? It also appears to wobble in the sky through a motion called #Libration. This video from NASA's Science Visualization Studio shows the apparent rolling motion of our Moon, due to its near 5° tilt and elliptical orbit. Learn more at moon.nasa.gov/observe

A grid showcasing twenty full moons, each captured monthly from May 2005 to December 2006. The images reveal the moon's varying size due to its elliptical orbit and subtle libration, showcasing a clear comparison of apparent size and a slight wobble over time.
