Scientists have discovered that Earth has temporarily gained a second moon, although the tiny asteroid is expected to leave our planet’s orbit within the next few months.
The space rock, officially identified as 2026 QQ8, measures just 3 to 6 feet across, making it smaller than most cars.
Despite its size, astronomers have classified the object as a temporary mini-moon due to its gravitational relationship with Earth.
The asteroid reportedly entered Earth’s gravitational influence in April 2026 but wasn’t discovered until late August, when Hungarian astronomer Kriztián Sárneczky identified it. Its stay is expected to end in late 2026 or early 2027.
Earth’s new mini-moon is expected to disappear within months
According to reports from The Independent and AccuWeather, asteroid 2026 QQ8 is expected to complete its temporary journey around Earth before returning to interplanetary space.
The object typically approaches Earth once every decade or so, but its latest encounter brought it close enough to become temporarily associated with our planet.
In August, the asteroid made its closest reported approach to Earth, passing approximately 333,700 miles away. For comparison, Earth’s permanent Moon orbits at an average distance of roughly 239,000 miles.

Astronomers have also indicated that the asteroid poses no danger to Earth. Even if its trajectory brought it into the planet’s atmosphere, the small space rock would likely burn up before reaching the surface.
While the discovery of another moon might sound unusual, temporary natural satellites are not unprecedented.
Astronomers observed an early example of a temporary mini-moon in 1991, and similar objects have been identified in the decades since.
Some researchers believe Earth could have as many as six mini-moons at any given time, according to BBC’s Sky at Night Magazine, although their small size makes them difficult to detect.
Unlike Earth’s permanent Moon, these objects only remain near the planet temporarily before continuing their journeys through space.
The discovery comes after astronomers identified another unusual companion to Earth, known as 2025 PN7, which had been traveling alongside our planet for decades before researchers noticed it.
Unlike temporary mini-moons such as 2026 QQ8, 2025 PN7 is classified as a quasi-moon because it orbits the Sun rather than Earth. Scientists believe the object has been following a similar orbital path to our planet for roughly 60 years and could remain nearby for several more decades.
