There are five points in space, called lagrangnian points l1 to l5, where the gravity of the sun and earth exactly cancels out each other. objects residing at these points are in some sort of gravitational equilibrium. more intriguingly, probes can orbit about these lagrangnian points even if no object is present there
以太陽和地球為例，太陽和地球之間的重力在5處不同的地方剛好互相抵消，稱為拉格朗日點l1 - l5 ，物體可以停留在拉格朗日點中而不受重力影響，即使點中沒有物質，物體也可以圍繞拉格朗日點公轉。 -
