– There are five such points (L1, L2, L3, L4, and L5).
– Points L4 and L5 are located 60 degrees ahead of and behind the smaller body (Earth in this case) in its orbit around the larger body (Sun), respectively.
– The distances from L4 (or L5) to the Sun and to the Earth are equal to the distance between the Sun and the Earth.
– This geometric arrangement forms an equilateral triangle with the two large bodies at two vertices and L4 (or L5) at the third vertex.
