Earth may have just gained a new companion in space — and NASA scientists are calling it a “second moon.” Discovered on August 2, 2025, by the Pan-STARRS telescope in Hawaii, asteroid 2025 PN7 has been quietly following Earth’s orbit for decades, moving in a synchronized path that makes it look like a second satellite.
Technically, Earth still has one true moon. But 2025 PN7 behaves like a “quasi-moon” — a small asteroid orbiting the Sun at nearly the same speed and distance as Earth. This creates an illusion that it’s orbiting our planet. Astronomers say it’s been keeping pace with Earth for about 60 years and will continue to do so until around 2083.
In 2025, Earth temporarily has a second companion. While it’s not a true moon, NASA confirms that 2025 PN7 behaves like one. It belongs to a rare group of objects called Arjuna asteroids, which share nearly identical orbits to Earth. These objects are extremely hard to detect due to their small size and faint visibility.
NASA has confirmed that large asteroids — including the infamous Apophis — will safely pass by Earth in 2029, 2036, and 2068. Despite online rumors, none pose a collision risk. Apophis, which once sparked doomsday predictions, will pass within 20,000 miles of Earth in April 2029 — closer than many satellites — but will not impact the planet.
NASA’s 2025 alert focuses on improved asteroid-tracking systems. The agency has urged global readiness for “potential near-Earth encounters,” emphasizing observation, not panic. The discovery of 2025 PN7 highlights how many small asteroids remain undetected in near-Earth orbit.
There is currently no asteroid predicted to hit Earth in 2025. NASA’s Planetary Defense Coordination Office monitors thousands of objects, and none are on a collision course. However, scientists continue to study smaller, fast-moving space rocks that could enter Earth’s atmosphere harmlessly as fireballs.
Asteroid 2009 FD once had a 3% estimated impact probability for the late 2100s, but newer observations reduced that risk to nearly zero. Modern tracking methods continue to update these probabilities as data improves.
According to NASA, no catastrophic solar event is expected in 2036. However, scientists predict increased solar flare activity as part of the Sun’s natural 11-year cycle, which could briefly affect satellites and radio communication on Earth.
While 2025 PN7 moves in a synchronized orbit with Earth, it remains gravitationally bound to the Sun, not our planet. However, its stability offers valuable insights into how natural satellites form and how space rocks interact with planetary orbits.
FAQs
Has NASA officially named Earth’s second moon?
Yes, it’s designated 2025 PN7. It’s classified as a near-Earth asteroid and a quasi-satellite of Earth.
Will Earth have more moons in the future?
Possibly — astronomers occasionally discover temporary mini-moons that orbit Earth for a few months or years before drifting away.
Can an asteroid be captured as a permanent moon?
Only if it loses enough velocity and becomes gravitationally bound to Earth. Such an event is extremely rare.
How close is 2025 PN7 to Earth?
It stays several million kilometers away — far beyond the Moon’s orbit — but moves in near-lockstep with Earth’s path around the Sun.
