About Quasi-moon 2023 FW13,Earth's Heretofore Secret Companion - revised

Space rock 2023 FW13,also referred to as a Quasi-moon,was detected on 28 March 2023 by the Pan-STARRS telescope at Haleakala,Maui,Hawaii.Pan-STARRS stands for "Panoramic Survey Telescope and Rapid Response System."It consists of telescopes and cameras dedicated to detecting near-Earth celestial objects.2023 FW13 is believed to have been Earth's companion since about 100 BC and will continue to circle Earth,in the course of 2023 FW13's elliptical orbit around the Sun,until at least 1500 years from now,in around 3700 AD.Controlled not by Earth's gravity,but by the Sun's,it will not likely be a hazard to Earth,since it travels in a wide ellipse largely,if not entirely,beyond the influence of Earth's gravity.Gravitational control areas are called Hill spheres.It is unlikely that Quasi-moons are affected by Earth's gravity at all. Some Quasi-moons are possibly near-Earth asteroids.After being detected by Pan-STARRS,2023 FW13 was confirmed by a number of other telescopes.Then it was officially listed by the Minor Planet Center of the International Astronomical Union (IAU).2023 FW13 has an estimated diameter of only 30-50 ft/10-15 m.2023 FW13 will hopefully continue to be studied by scientists who can ascertain its composition. Quasi-moons are also called Quasi-satellites.Space rock 2016 HO3 was detected in April 2016.Light reflected by it was analyzed and the results suggest it is composed of the same material as the Moon rocks brought back by the Apollo missions.So it could be a fragment of the Moon.It's only in recent times that we've become aware of Earth's previously secret companions through increasingly rigorous sky surveys.
