Mystery of the asteroids around Jupiter: scientists propose new clue

New study offers another explanation for Trojan asteroids' numerical asymmetry.

An international team of scientists, including researchers from the US, Japan and China, have proposed a new theory that could explain the numerical asymmetry of Jupiter's Trojan asteroids, which are located at the L4 and L5 Lagrange points. Both of these asteroid clusters are made up of more than 10,000 space rocks orbiting Jupiter around the Sun, writes Phys.

Two groups of asteroids are called the Trojan asteroids due to the fact that many of them are named after the heroes of the Trojan War, which is described by Homer in the Iliad. Asteroids that are located at the L4 Lagrange point were named after the Greeks who stormed the city of Troy, and asteroids from the L5 Lagrange point were named Trojans.

For decades, astronomers have been trying to understand why Jupiter's Trojan more stones than the group at point L5. The exact reason for this numerical asymmetry has not yet been established, but an international team of scientists has proposed a new theory.

In the current configuration of the solar system, both groups of asteroids have the same properties and “behavior” in space. Therefore, scientists decided that most likely the differences between the two groups arose in earlier periods of the history of our star system.

According to scientists, if the reasons for these differences are understood, then such a discovery can provide new information about the formation and evolution of the solar system. systems. Therefore, the researchers presented a mechanism that could explain the observed asymmetry between the Trojan asteroid groups.

The scientists speculate that the rapid movement of Jupiter may have distorted the configuration of the Trojan asteroids, resulting in more stable orbits in the L4 group than in the L5 group. Such a mechanism, which temporarily caused different evolutionary paths for the two groups of asteroids that share the orbit of Jupiter, provides a new explanation for the fact that there are about 1.6 times more asteroids in the L4 group than asteroids in the L5 group.

Scientists have created a model of the early solar system, the orbits of the planets were not the same stable, causing Jupiter to move much farther away from the Sun. This is what influenced the stability of the orbits of the asteroids located here. Scientists also do not exclude the influence of other planets, but this will already be the subject of future research.

As Focus already wrote, not only Jupiter has Trojan asteroids. Two similar space rocks revolve around the Sun in the same orbit as the Earth. And on one of them you can build a space base.

As for ordinary near-Earth asteroids, Focus already wrote that two large space rocks swept past our planet at great speed.< /p>
