earth Briefly Had Two Moons, Captured Asteroid Became Temporary Companion
London, UK – For a short period in 2023, Earth had two moons. A small asteroid, designated 2023 FW13, was temporarily captured by our planet’s gravity, effectively becoming a “mini-moon” alongside our familiar lunar companion.While the phenomenon isn’t unprecedented, the recent observation adn tracking of 2023 FW13 have sparked renewed interest in the dynamics of near-earth objects and the complex gravitational interactions within our solar system.
The asteroid, estimated to be between 6.2 and 18.3 feet in diameter, entered Earth’s orbit around September 2023 and orbited our planet for several weeks before escaping back into its own orbit around the sun. This event highlights the constant stream of space rocks that come close to Earth, and the possibility - though rare – of temporary captures. Astronomers beleive 2023 FW13 is not a threat to Earth, but its brief companionship offers a unique prospect to study the formation and behaviour of small celestial bodies.
The discovery was made by astronomers at the Pan-STARRS observatory in Hawaii, who tracked the asteroid’s unusual trajectory. “It was a realy captivating object,” explained Paul Chodas, manager of NASA’s Center for Near Earth Object Studies, to Metro. ”It’s very common for small asteroids to be captured temporarily by planets,but it’s not so common to actually get a good look at them.”
While 2023 FW13 has since departed, the event underscores the dynamic nature of our solar system. Earth has hosted other temporary moons in the past, and scientists predict more will be discovered as observational capabilities improve. These mini-moons provide valuable insights into the early solar system and the processes that shaped the planets we no today.
