Lagrangian point

(redirected from Lagrange point)

La·gran·gi·an point

Astronomy Any of five points in the orbital plane of two bodies, one of which is much larger than the other, at which a third, even smaller body will remain in gravitational equilibrium. Bodies located at Lagrangian points appear stationary with respect to the larger two bodies. Also called Lagrange point.

[After Comte Joseph Louis Lagrange.]

Lagrangian point

(Astronomy) astronomy one of five points in the plane of revolution of two bodies in orbit around their common centre of gravity, at which a third body of negligible mass can remain in equilibrium with respect to the other two bodies

It will be positioned near the second Lagrange point (L2) of the Earth-Sun system.
These structures would hover around Earth at the Lagrange point - the altitude at which the Moon and Earth exert equal-but-opposite gravitational forces.
Then finally, on Saturday the Russian space agency successfully launched it out of Earth's orbit and onto the ( L2 Lagrange point.
Roscosmos said the telescope, named Spektr-RG, was delivered into a parking orbit before a final burn Saturday that kicked the spacecraft out of Earth's orbit and on to its final destination: the L2 Lagrange point, according to the Associated Press (AP).
Spektr-RG will next navigate to a stable orbit in space called a Lagrange point (specifically, L2), where the gravitational forces of two large objects -- in this case, the sun and the Earth -- balance each other out.
As per the observatory's schedule, Spektr-RG will cruise to the Lagrange Point 2 located 1.5 million kilometres from Earth before beginning a 4-year all sky survey.
The SPICA Observatory will be launched on an H3 rocket for a nominal mission of 3 years orbiting the second Lagrange point of the SunEarth system (SEL2).
The story begins at L1 Lagrange Point, the 'neutral gravity point' where the pull of the sun equals that of our planet.
The so-called Lagrange Point, also known as L1 appears to be the best.
NASA Planetary Science Division director Jim Green stated that a powerful magnetic bipole placed at Mars' L1 Lagrange Point could deflect solar winds.
DSCOVR recently reached its station about a million miles away between the Earth and the sun at a Lagrange point, where gravitational fields of Earth and Sun cancel out.
DSCOVR will travel to the so-called Lagrange point, or L1, a spot 1 million miles from Earth and 92 million miles from the sun, where the gravity fields are neutralized.
