    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 ...
