The Visualization Lagrange Point In The Solar-System

With the continuous development of deep space exploration in China,the research and application of Lagrange points have become more and more important.And the research of Lagrange points has gradually been promoted from theory to practice.China became the third country to visit Lagrange L2 after the United States and the European Union.Chang'e-4 became the world's first spacecraft to land and patrol on the back of the moon.Its communication mainly relies on its relay satellite "Que Qiao".This satelite's orbit is the Halo orbit of the earth-moon L2 translation point on the back side of the moon.The "Que Qiao" satellite makes a pseudo-circular motion at the L2 point of Lagrange,and maintains the stability of the orbit through regular orbit control.China's future Mars exploration mission also proposed a plan to build relay communication satellites at Lagrange points L4 and L5.The major powers have also stepped up research on the Lagrangian point.NASA plans to create a space station at the ground moon Lagrange point L2,and the European Space Agency(ESA)uses the ground moon Lagrange point L1 Capturing asteroids to obtain space resources,etc.,the competition for Lagrange points among nations has become more intense.According to the above situation and combined with China's national conditions.This article first introduces the research and application status of Lagrange points at home and abroad,then analyzes the main stars in the solar system,studies the Lagrange points formed by them and the sun,and visualizes them from theoretical and computer simulations.
