About L5

Lagrange 5 is a portal to Internet news and sites about space and spaceflight. It evolved from a series of similar sites hosted from GeoCities since 1999.

Lagrange points are five points in space around two gravitational bodies (such as the earth and the moon), where future spacecraft will be able to achieve "fixed" orbits. The most stable of these points are L4 and L5. Each of these are equidistant from the earth and the moon, so that the forces between the objects are balanced.

Lagrange points are named for Italian-born French mathemetician Joseph Louis Lagrange (1736-1813), who discovered them. They are considered ideal staging areas for future exploration within the solar system.
