Earth might gain another Moon, a miniature one, due to a rare phenomenon called gravitational trapping. Carlos de la Fuente Marcos and Raúl de la Fuente Marcos, researchers from Universidad Complutense de Madrid, have announced an intriguing celestial event.
In a rare celestial event, a ‘mini-moon’ will revolve around our planet Earth for two months. An asteroid will be captured by Earth’s gravity and will orbit our planet from September 29 to November 25 this year. According to a report published in the Research Notes of the American Astronomical Society, Asteroid 2024 PT5 was discovered on 2024 August 7 by the Asteroid Terrestrial-impact Last Alert System. With a size of 10 metre, the asteroid follows a horseshoe path and will not make a full orbit.
The researchers also estimated the asteroid's origins, suggesting it is likely from the Arjuna asteroid belt. This belt is known for containing asteroids with orbits similar to Earth's. The analysis indicates that 2024 PT5 is not space debris but rather an object of natural origin, given its trajectory resembles that of other natural celestial bodies.
This brief encounter with 2024 PT5 provides a unique opportunity for researchers to study such interactions and enhance our understanding of asteroid behaviour in our solar system.
