Asteroid 2025 PN7 was detected in Hawaii and is expected to accompany Earth until 2083, creating the illusion of a second moon
Have you ever imagined looking up at the sky and seeing two moons? A new study published by the American Astronomical Society revealed the 2025 discovery PN7a small asteroid about 19 meters in diameter that will pass share Earth’s orbit for the next 58 years. Recently discovered by astronomers in Hawaii, the object was characterized as a “quasi-moon” as it follows a trajectory very similar to that of our planet around the Sun. Although it does not orbit the Earth directly, the synchronized motion creates the illusion that the sky has gained a second moon, even though it is invisible to the naked eye.
Study reveals discovery of a ‘quasi-moon’
Confirmation of the existence of 2025 PN7 was announced by the American Astronomical Society, following observations made on the Pan-STARRS telescope at the Haleakalā observatory, located in Hawaii, in August this year. The object is very small, about 19 meters in diameter, and belongs to the group of asteroids known as Arjuna, characterized by orbits very close to Earth.
Scientists believe that 2025 PN7 has accompanied the planet for decadesbut because it is very small, it has only now been detected thanks to technological advances in astronomical telescopes and cameras. The research, conducted by two Spanish astronomer brothers, Carlos and Raúl de la Fuente Marcos, by Complutense University from Madrid, Spain, describes the phenomenon as one of rarer among those characterized as “quasi-moon”objects that appear to orbit around the…
