Scientists announced the discovery of 2025 PN7, a quasi-moon sharing Earth's orbit for about 60 years. This 19-meter-wide asteroid is primarily influenced by the Sun's gravity but appears to orbit Earth from our perspective.
The announcement came on September 10, 2025, revealing that 2025 PN7 has been a temporary companion to Earth. Quasi-moons are asteroids that follow horseshoe orbits relative to planets.
Significance
- Orbit duration: 60 years.
- Not a true moon, but co-orbital object.
- Enhances understanding of near-Earth asteroids.
