Earth has officially been joined in its orbit around the Sun by a new trojan asteroid.
asteroids are darker in hue because they're rich in carbon. They're also the most numerous asteroids in the Solar System; more than 75 percent of all Solar System asteroids could be carbonaceous. They're among the oldest objects in the Solar System, with a composition similar to that of the Sun itself.
This makes C-type asteroids an attractive target for studying the early Solar System and the formation of the planets, and Earth trojans potentially even more so. We currently have several space observatories" " in Earth-Sun Lagrange points; having a C-type asteroid hanging about nearby within reach would be an excellent opportunity.VenusAny object orbiting the Lagrangians would be moving around a lot, leaving a very large patch of sky to scour looking for relatively small objects; having two Earth trojans to study will give astronomers a bigger toolkit for calculating those orbits.
In turn, that could help us find a population of potentially hundreds of Earth trojans, lurking out there in the dark. "If we are able to discover more Earth trojans, and if some of them can have orbits with lower inclinations, they might become cheaper to reach than our Moon,""So they might become ideal bases for an advanced exploration of the Solar System, or they could even be a source of resources."
