New theory for Jupiter asteroid⁘

An international team of scientists, including NYU Abu Dhabi researchers, and others from the United States of America,

Japan, and China, has developed new insights that may explain the numerical a symmetry f l4 and L5 Jupiter trojan swarms, 2 clusters containing more than 10,000 asteroids that move along Jupiter's orbital path around the sun.

For decades, scientists have known that there are significantly more asteroids in the L4 swarm than in the L5 swarm but have not fully understood the reason for this asymmetry. in the current configuration of the solar system, the 2 swarms show almost identical dynamical stability and survivability properties. scientists propose an outward in terms of distance to the sun fast migration of Jupiter can distort the configuration of trojan swarms, resulting in more stable orbits in the L4 swarm than the L5. this mechanism, which temporarily induced different evolution paths for the 2 asteroids groups that share the orbit of Jupiter, provides a new explanation for the unbiased observations, that the L4 asteroids are about 1.6 times more than the L5 swarm...
