The 2nd Sun-Earth Lagrange point (L2) is situated some 1.5 million km from the Earth on the line defined by the Sun and Earth. At L2, the outward directed force from the rotation around the Sun counterbalances the gravitational attraction by the Earth, Moon and Sun. Euclid will rotate in an orbit around L2; this orbit, which has a diameter of about 1 million kilometres, is roughly situated in a plane perpendicular to the Sun-Earth line.
