Earth temporarily captures tiny asteroid as new mini-moon
Astronomers have identified a small asteroid designated 2026 QQ8 that entered Earth's gravitational pull in April and will remain in orbit until early 2027. The celestial visitor poses no collision risk to our planet.

A diminutive asteroid has joined Earth's collection of temporary natural satellites after being gravitationally captured in April 2026. Designated 2026 QQ8, the space rock was first observed and confirmed by astronomers in August, marking its formal identification as a natural celestial body now orbiting our planet.
The mini-moon is expected to remain within Earth's gravitational influence for approximately eight to nine months, making its departure sometime in early 2027. This transient status is typical for such small asteroids, which occasionally pass through the inner solar system and become temporarily bound to our planet before continuing their journey through space.
Astronomers have calculated that the asteroid's closest approach to Earth will occur at a distance of 568,000 kilometers—substantially farther than the Moon's orbit and well beyond any risk of collision. This safe distance ensures that 2026 QQ8 poses no threat to Earth-based infrastructure or human activities, despite its temporary proximity to our planet.
The discovery adds to a growing catalogue of mini-moons that periodically orbit Earth before breaking free. Such transient satellites provide valuable opportunities for scientists to study near-Earth asteroids and better understand the dynamics of objects moving through our corner of the solar system.
