Asteroid 2023 FW13 has been named a “semi-moon” or “semi-satellite,” meaning
It orbits the Sun in a similar period of time as Earth, but is only slightly affected by our planet’s gravity.
2023 FW13, which has a diameter of 15 meters, is also orbiting Earth and is approaching our planet at a distance of 14 million km. Life Science.
The asteroid was first detected by the Pan-STARRS observatory in Hawaii in March. The existence of the “quasi-moon” was confirmed by the Canada-France-Hawaii Telescope and two observatories in Arizona before it was officially added to the list of planets and moons in the solar system by the International Astronomical Union’s Asteroid Center in April. 1.
By some estimates, 2023 FW13 has been Earth’s cosmic neighbor since at least 100 BC, and will continue to follow its current orbit for a long time to come — until about 3,700, according to astronomer and journalist Adrien Coffinet, who first cataloged the asteroid.
It appears to be the longest known semi-satellite of Earth

By the way, 2023 FW13 isn’t the only companion to Earth; Another “semi-satellite” was also discovered in 2016. The His name is Kamo’oalewa The celestial body is moving similarly near Earth — in fact, according to a 2021 study, this asteroid may actually be part of Earth’s moon.
Perhaps the danger is one of them asteroid It does not threaten us either: as we wrote earlier in the index, according to NASA, in the next 100 years, there is no need to fear an asteroid hitting the Earth.
