As we marvel at the mysteries of our universe, 2024 PT5 serves as a reminder of the dynamic and ever-changing nature of our cosmic neighborhood.
Earth Welcomes a Temporary “Mini-Moon”
The universe is full of wonders, and today, Earth has gained a brief companion in the form of a “mini-moon.” This phenomenon occurs when a smaller celestial body enters Earth’s orbit, even if only for a short time.
What is a Mini-Moon?
A mini-moon is typically an asteroid that becomes temporarily trapped by Earth’s gravity. The latest addition, known as 2024 PT5, will orbit our planet starting today, September 29, and remain until November 25. This marks the fifth mini-moon detected by scientists, following the first, 1991 VG, discovered in 1991.
The Journey of 2024 PT5
Manish Purohit, a former scientist at ISRO, explains, “The tiny asteroid 2024 PT5 has been drawn to Earth after a long journey through space. Our planet’s gravity has influenced its path, turning it into a temporary companion.”
While 2024 PT5 is classified as a mini-moon, it will not complete a full orbit around Earth. Instead, it will travel in a horseshoe trajectory for approximately 55 days before escaping our planet’s gravitational pull.
Characteristics of the Mini-Moon
2024 PT5 originated from the Arjuna asteroid belt and measures about 10 meters (33 feet) in diameter. Due to its size, it won’t be visible to the naked eye. Observers will need special telescopes to catch a glimpse of this celestial body.
The Rarity of Mini-Moons
Many asteroids pass close to Earth each year. However, only a select few get captured by our gravitational pull. Most either lack the size to be caught or veer too far away.
