punkt, kus kosmoselaev või väike taevakeha võib omada stabiilset orbiiti vaatamata kahe massiivse taevakeha gravitatsioonilisele tõmbele
the five points in the outer space where a small object can have a stable orbit in spite of the gravitational attractions exerted by two much more massive celestial objects
James Webbi kosmoseteleskoop on kavandatud töötama umbkaudu 5-10 aastat ja paiknema hakkab ta teises Lagrange'i punktis (L2), ligikaudu 1,5 miljoni kilomeetri kaugusel Maast.
Good to know
Nimetatud prantsuse matemaatiku, füüsiku ja astronoomi Joseph-Louis Lagrange'i (1736-1813) järgi.
The L1 point is perhaps the most immediately significant of the Lagrangian points, which were discovered by mathematician Joseph Louis Lagrange. It lies 1.5 million kilometres inside the Earth’s orbit, partway between the Sun and the Earth. Lagrangian points are where all the gravitational forces acting between two objects cancel each other out and therefore can be used by spacecraft to ‘hover’.
