Astronomers discovered the Arjuna 2025 PN7:
Astronomers discovered the Arjuna 2025 PN7, a new quasi-satellite of Earth; it was first spotted by the Pan-STARRS 1 telescope in Hawaii. 2025 PN7 belongs to the Arjuna asteroid class, named after the mythical figure Arjuna of the Mahabharata, symbolizing its fast, elusive nature. Quasi-Satellite Classification: 2025 PN7 is Earth’s seventh known quasi-satellite. These objects are considered quasi-moons because their orbits around the Sun closely follow Earth’s orbit, though they are not gravitationally bound to the planet. A quasi-satellite of Earth is an object that orbits the Sun in a similar path to Earth but is not gravitationally bound to Earth. Mini-moons and quasi-moons differ, while mini-moons orbit Earth temporarily, quasi-moons stay in sync with Earth’s orbit for hundreds to thousands of years. With a semi-major axis of 1.003 Astronomical Unit (AU) (almost identical to Earth’s orbit), 2025 PN7 follows a slightly elliptical orbit. 2025 PN7 orbits the Sun, not Earth, but stays near Earth due to a 1:1 orbital resonance, meaning it completes one orbit around the Sun in the same time as Earth.
