The term "mini-moon" refers to an asteroid known as 2024 PT5, which has been temporarily captured by Earth’s gravitational pull. This asteroid orbits the planet for a period of 57 days, behaving similarly to a small second moon.
Measuring approximately 10 meters in width, 2024 PT5 is comparable in size to a double-decker bus, making it a relatively small celestial body but significant in its unique role.
Discovered on August 7, 2024, the asteroid was identified by the Asteroid Terrestrial-impact Last Alert System (ATLAS) located in South Africa, marking an important find in the study of near-Earth objects.
Asteroid 2024 PT5 is categorized within the Apollo group, recognized as the largest collection of near-Earth asteroids. These asteroids are characterized by their paths that cross Earth’s orbit around the Sun.
This asteroid officially entered Earth’s orbit on September 29, 2024, and is projected to depart on November 25, 2024, completing a total of 56.6 days in orbit.
Indeed, asteroid 2024 PT5 is anticipated to make another pass by Earth in 2055, allowing scientists and enthusiasts alike to observe its trajectory once again.
No, 2024 PT5 is considered too small to inflict any significant damage upon Earth. It poses no threat, providing a unique opportunity for observation rather than concern.
The nickname "mini-moon" arises from its temporary orbit around Earth, despite being much smaller than our natural Moon. This designation highlights its brief existence as a satellite of our planet.
Asteroid 2024 PT5 is a remarkable example of a small celestial body being captured by Earth’s gravity to act as a temporary satellite. Such occurrences are rare, showcasing the cosmos' ability to surprise us. As noted, "the cosmos constantly reminds us of its surprises—small steps for humanity, giant leaps for understanding."
