This September, Earth will temporarily capture a small asteroid, named 2024 PT5, adding a new, albeit temporary, mini-moon to our planet’s celestial entourage. This event offers a rare glimpse into the dynamic and transient nature of Earth’s gravitational interactions with near-Earth objects.
2024 PT5, a small Arjuna asteroid, will enter Earth’s orbit for approximately two months starting this September. This phenomenon provides scientists with a unique opportunity to study near-Earth objects (NEOs) up close.
Discovered on August 7 by the Asteroid Terrestrial-impact Last Alert System (ATLAS) telescope in South Africa, 2024 PT5 hails from the Arjuna asteroid belt, which shares a similar orbit to Earth around the Sun.
The asteroid, measuring just 11 meters in diameter, will begin its temporary orbit around Earth on September 29, 2024, and is expected to leave by November 25, 2024. It will make a close approach again on January 9, 2025.
Due to its small size and faint magnitude (22), 2024 PT5 will not be visible to the naked eye or even through standard amateur telescopes. Only large, professional telescopes will be able to track this mini-moon.
The capture of 2024 PT5 offers astronomers a rare chance to study a temporarily captured object. These events help scientists understand the dynamics of NEOs and their potential impact risks to Earth.

While it’s not uncommon for Earth to attract quasi-satellites or engage in temporary gravitational interactions, each occurrence provides valuable data about our planet’s place in the cosmos and the ongoing dance with our solar system’s smaller inhabitants.
The arrival of 2024 PT5 as a temporary mini-moon highlights the dynamic nature of Earth’s relationship with nearby celestial objects. This event not only fascinates astronomers but also enhances our understanding of the mechanisms governing planetary orbits and asteroid behaviors.
In late September 2024, Earth will temporarily capture a small asteroid, 2024 PT5, marking it as an additional but brief mini-moon. This event provides a unique observational opportunity for astronomers and adds another chapter to our understanding of near-Earth objects and their interactions with our planet.
