Recently, astronomers recorded a new object, which is now considered a quasi-moon of Earth — 2025 PN7. This temporary satellite attracted the attention of specialists due to its unique motion and orbital characteristics. Quasi-moons are interesting not only from a scientific perspective but also as potential objects for future space research.
What a Quasi-Moon Is
A quasi-moon is a celestial body that temporarily orbits Earth, moving along with it around the Sun. Unlike the regular Moon, a quasi-moon is not permanently fixed in orbit and may eventually leave the planet’s gravitational field. These objects give scientists the opportunity to study the dynamics of near-Earth bodies and gravitational interactions. Read also: A new island has formed in the middle of a glacier in Alaska
Features of Quasi-Moon 2025 PN7
The object 2025 PN7 was discovered using modern telescopes and astronomical surveys. Its orbit is unusual: the body moves along an elliptical trajectory, periodically approaching Earth and then moving away to a distance comparable to the Moon’s orbit. The size of 2025 PN7 is small — only a few dozen meters in diameter, making it visible only with professional equipment.
Scientific Value of the Discovery
Studying quasi-moons such as 2025 PN7 helps astronomers:
- analyze the dynamics of small body orbits;
- predict potential close approaches to Earth;
-
study the composition of asteroids near the planet.
In addition, such objects are considered potential candidates for future space missions, as they are relatively easily accessible for spacecraft.

Observation and Mission Prospects
In the coming years, astronomers plan to observe 2025 PN7 using ground-based and orbital telescopes. This will allow them to refine the object’s orbital parameters, rotation, and physical characteristics. Theoretically, the quasi-moon could become an intermediate target for small research missions aimed at studying asteroids and testing new technologies.
Impact on Earth
Despite its proximity to our planet, quasi-moon 2025 PN7 poses no threat to Earth. Its orbit is stabilized so that the object periodically moves away from the planet, ensuring safe interaction. Nevertheless, monitoring such bodies is important for predicting possible changes in their trajectories. We previously reported that NASA had discovered the clearest signs of life on Mars.
Interesting Facts About Quasi-Moons
Quasi-moons are rare and fascinating phenomena. Other temporary satellites of Earth have been recorded previously, but each new object, including 2025 PN7, provides unique scientific data and expands our knowledge of the planet’s cosmic environment.
