Why in News?

Asteroid 2024 PT5 recently passed close to Earth without causing any harm, and another asteroid, resembling a mini-moon is approaching.

About 2024 PT5

Earth AND MINI MOON

1. About: 2024 PT5 is an asteroid, measuring 33 feet in length. It will soon be captured by Earth’s gravity. It is not a true mini-moon. It will follow a horseshoe-shaped orbit.

2. The asteroid will be temporarily caught by Earth’s gravitational pull and will remain in orbit for approximately 56 days.

3. Duration: 2024 PT5 will start its journey around Earth on September 29, 2024, and will break free by November 25, 2024, continuing its cosmic trajectory.

4. Scientific Significance: 2024 PT5 offers a unique opportunity to study objects that frequently pass near Earth. Scientists suggested that 2024 PT5 might be a fragment of lunar ejecta, adding further interest to its origin.

5. Discovery and Observation: The asteroid was first detected on August 7, 2024, by the Asteroid Terrestrial-impact Last Alert System. 2024 PT5 will only be visible through specialized telescopes due to its small size

6. Resource Exploration Potential: Some mini-moons may contain valuable metals, making them attractive for future mining if they are captured by Earth’s gravity.

About mini moon

1. A “mini moon” refers to a small object that temporarily orbits a planet, in this case, Earth.

2. These mini moons are typically small asteroids that get captured by Earth’s gravity and orbit it for a period before either being flung back into space or burning up in the atmosphere.

3. They are significantly smaller than the Earth’s actual moon, often just a few meters in diameter.

4. Mini moons are rare and typically short-lived in Earth’s orbit due to the influence of gravitational forces from the Sun, Earth, and the Moon.
