Two important Lagrange points in the Sun-Earth system are L 1, between the Sun and Earth, and L 2, on the same line at the opposite side of the Earth; both are well outside the Moon's orbit. Currently, an artificial satellite called the Deep Space Climate Observatory (DSCOVR) is located at L 1 to study solar wind coming toward Earth from the ...
Lagrangian point missions Mission Lagrangian point Agency Description International Sun–Earth Explorer 3 (ISEE-3) Sun–Earth L 1: NASA: Launched in 1978, it was the first spacecraft to be put into orbit around a libration point, where it operated for four years in a halo orbit about the L 1 Sun–Earth point.

The Kordylewski clouds are located near the L 4 and L 5 Lagrange points of the Earth–Moon system. They are about 6 degrees in angular diameter. [7] The clouds can drift up to 6 to 10 degrees from those points. [11] Other observations suggest they move around the Lagrange points in ellipses of about 6 by 2 degrees. [7]
Position of 2010 TK 7 relative to Earth in 2011 Effective potential plot showing Earth's Lagrangian points (not to scale); contours around L 4 and L 5 represent tadpole loop paths. Because Earth trojans share Earth's orbit and have little gravity of their own, less energy might be needed to reach them than the Moon, even though they are much ...

India's space agency ISRO launched Aditya-L1 to study the sun from a halo orbit around L 1 point. [11] On 6 January 2024, Aditya-L1 spacecraft, India's first solar mission, has successfully entered its final orbit with a period of approximately 180 days around the first Sun-Earth Lagrangian point (L1), approximately 1.5 million kilometers from ...
