Astronomers have discovered an object that is being referred to as a "quasi-moon" that shares earth's orbit around the sun. The object, identified as 2025 PN7, is described as a temporary companion to earth, but it is unclear how long it will remain in this orbit, with some reports suggesting it could last until 2083. The discovery has sparked debate over whether earth can be said to have a "second moon," with some outlets reporting that there may be multiple such quasi-moons.
