The image of Mars and the retrieval of its Trojans revolve around the L4 and L5l range range points. The curved curve detects the orbit of the planet. At L5, the asteroid 101429 is represented by Blue Point, the asteroid Eureka and its family are represented in red and amber, respectively. Credit: Armagh Observatory
An international team of planetary scientists led by astronomers at AOP is finding the back of the planet Mars With a similar formation to the moon. Asteroids may be an ancient piece of debris, composed of the vast effects that formed the moon and other rocky planets in our solar system, such as Mars and Earth. Research, which was published in the journal Icarus, Also has implications for discovering such primitive objects associated with our own planet.
Trojans are a class of asteroids that follow planets in their orbits as flocks of sheep follow a shepherd, trapped inside gravitational “safe havens”, 60 degrees forward, and backward, the planet (Figure 1). They are of great interest to scientists because they represent the material left over from the formation of the solar system and early evolution. It exists in the orbit of many thousands of Trojan giant planets Jupiter. Near the Sun, astronomers have so far discovered only a handful of Trojans from the Earth’s front door, the planet Mars.

The conspiracy was hatched against the spectrum of the area surrounding the Litro crater near the Apollo 17 landing site on the moon, obtained from the Mauna Kea Observatory in Hawaii.

Where can such an unusual thing come from? One possibility is that 101429 is another asteroid, similar to a normal chondrite meteorite that achieved a moon-like appearance exposed to solar radiation, a process called space weather.
Alternatively, the asteroid will look like the moon because it comes from the moon. A.O.P. The astronomer and lead author of the paper, Dr. Apostolos Cristo explains: “The early solar system was very different from what we see today. The space between the newly formed planets was full of debris and collisions were a common occurrence. Larger asteroids – what we call these planets – were constantly colliding with the Moon and other planets. Such a collision could have reached the orbit of Mars when the Earth was still forming and its Trojans were trapped in the clouds. ”
Third, and probably scenario, the probable scenario is that the object came from Mars. Dr. Christ. “The shape of the 101429 spectrum tells us that it is rich in pyroxene, a mineral found in the outer layer or crust of a planet-sized body,” Cristo said. Mars, like the Moon and Earth, was disturbed by the early effects of its history, one of which was responsible for the vast, Boralis Basin, which was as wide as the planet. Such a tremendous effect could easily send 101429 to go to the planet’s L5 lagerian point. “Indeed, a few years ago, the origin of Mars was proposed for the Trojan siblings of 101429, a group of Trojans collectively known as the Eureka family (Figure 1). These asteroids also have an unusual composition but The asteroids of the family are mostly olivines, found deep in the mantle of mineral planets.
101429 and his brothers also have something to teach them to find the Earth Trojan, if it exists. Previous work by the team has shown that solar radiation causes debris, in the form of boulder- or city-block-sized parts, to slowly emerge from these asteroids out of Mars’ Trojan clouds. If Earth is nothing like Trojan Mars, the same mechanism will act as a source of small-Earth asteroids that will also stand out due to their unusual composition.
Finding these objects is a tax. The Rubin could be a job for the observatory, which is preparing for the most ambitious survey of the solar system to date. Rubin now expects to find ten times as many known asteroids, and with the GAIA satellite already surveying the sky from the L2 Earth-Sun range range grease point, it could offer us the best possible time to find Earth’s debris. Trojan allies.
