Two probes will explore the early Solar System

“The points derive from the three-body problem, which considers the gravitational pull of just two bodies (in this case, the Sun and Jupiter), and then the few points where smaller points can remain stable are found through algebraic methods. The Trojan asteroids are celestial bodies that gathered around Jupiter's L4 and L5. The Lucy mission is crucial to understanding the history of the solar system.”
