2024 holds many surprises and cosmic wonders. According to NASA scientists, the Earth will soon get a second satellite thanks to an asteroid being pulled by its gravity. The event is expected to be a rare and mesmerizing phenomenon that will captivate stargazers around the world.

However, unless you have a professional telescope, this mini-moon will be less bright and smaller. The space visitor will stay on Earth for a few months starting September 29 before escaping Earth’s gravity again.
You are watching: What is 2024 PT5? Will it be Visible from India?
The asteroid 2024 PT5 comes from the Arjuna asteroid belt, which contains rocks with orbits very similar to those of Earth. The asteroid, about 10 meters (33 feet) in diameter, will be captured by Earth’s gravity between September 29 and November 25, 2024.
What is 2024 PT25, Earth’s new “mini” moon?
PT25 is not a moon, but a 10-meter asteroid from the Arjuna asteroid belt, which contains rocks with orbits very similar to Earth’s. The Arjuna asteroid belt is a group of asteroids in the solar system that are specifically classified as near-Earth objects (NEOs).
The belt consists of asteroids with orbits similar to Earth’s, typically about 93 million miles (150 million kilometers) from the sun. These asteroids have low-inclination orbits with a period close to one year, making their paths around the sun very Earth-like.
Sometimes, Earth’s gravity can pull objects in Arjuna’s belt into its orbit, turning them into “mini-satellites” or transient satellites. For example, starting on September 29, 2024, Earth will capture asteroid 2024 PT5 for about two months.
Experts on the study claimed that if an asteroid of this size was traveling at a moderate speed of about 2,200 mph (3,540 km/h), Earth’s gravitational field could have a significant impact and briefly capture it. That’s exactly what’s going to happen; the tiny asteroid will begin its roughly two-month orbit around Earth this weekend.
Key details for 2024 PT5
- Discovery: The asteroid was discovered on August 7, 2024, by the Asteroid Terrestrial Impact Final Alert System (ATLAS) at Haleakala Observatory in Hawaii.
- Orbital Characteristics: Unlike the permanent moon, 2024 PT5 will follow a horseshoe-shaped path around Earth rather than completing a full orbit. This is due to its relatively slow approach speed and trajectory.
- Visibility: The mini-moon is too faint to be seen with the naked eye or a small telescope, but can be observed with larger telescopes during its brief stay.
What is a mini moon?
Mini-moons are essentially asteroids that are temporarily affected by Earth’s gravity. They vary in size and typically stay in orbit for months to years before escaping back into space. Captures of such objects are relatively rare, occurring on average approximately every 10 to 20 years.
Types of mini satellites
- Temporarily captured orbiters: These mini-satellites complete at least one full orbit around the Earth before escaping. For example, 2006 RH120, a small moon orbited the Earth for about a year from July 2006 to 2007.
- Improvised flybys: They do not complete a full orbit, but instead follow a horseshoe-shaped path around the Earth. For example, 2024 PT5 is currently scheduled to be captured from September 29 to November 25, 2024, and it will not complete a full orbit. 2020 CD3 is a mini-satellite that stayed in Earth’s orbit for several years before departing in May 2020. The 2022 NX1 follows a similar trajectory and is expected to return in the coming years.
feature
- Mini-satellites typically range in size from a few meters to tens of meters across.
- Due to their small size and low brightness, they are often difficult to detect, making observations challenging.
- Mini-satellites are captured approximately every 10 to 20 years, underscoring their rarity.
Can 2024 PT25 be seen from India?
Unfortunately, the 2024 PT25 cannot be seen from India or any other country, as it is approximately 10 meters (33 feet) in diameter. It is too small and dim to be seen with the naked eye, binoculars, or a standard telescope. Only professional astronomers with large telescopes can effectively study it.
What PT25 means in astronomy in 2024
The astronomical significance of asteroid 2024 PT5 lies in several key aspects:
1) Temporarily capture dynamics
Classified as a mini-satellite, 2024 PT5 is a temporary satellite that will be captured by Earth’s gravity between September 29 and November 25, 2024. This provides a unique opportunity to study the dynamics of how asteroids are temporarily captured by planets, thereby enhancing our understanding of gravitational interactions in the solar system.
2) Insight into Near-Earth Objects (NEO)
The asteroid is part of the Arjuna asteroid group, which consists of near-Earth objects with similar orbits to Earth. Studying 2024 PT5 will help astronomers collect data on the composition, structure and behavior of near-Earth objects, contributing to broader research into potential hazards and the history of the solar system.
3) Comparative analysis
With an estimated size of 10 to 42 meters (33 to 138 feet), 2024 PT5 may be larger than the asteroid that exploded over Chelyabinsk, Russia, in 2013. This comparison allows scientists to analyze the potential impact risks associated with asteroids of similar size. object.
4) Future observations
After a brief stay, 2024 PT5 is expected to make another close approach in January 2025 and return as mini-moons in 2055 and 2084. These future encounters will provide additional opportunities for observation and research, allowing astronomers to track its trajectory and understand its trajectory. Changes over time.
How often do mini-moons like 2024 PT5 occur?
Mini-satellites like 2024 PT5 appear relatively frequently, with multiple short-term captures occurring every decade. However, long-term capture (where an asteroid remains in orbit for a year or more) is much rarer, typically occurring every 10 to 20 years.
Event Summary
- Short-term catches: a few times per decade.
- Long-term capture: every 10 to 20 years.
