Earth's newest mini-moon, the 1–2-metre asteroid 2026 QQ8, is expected to remain under the planet's gravitational influence only through December, breaking free around the end of the year or in early January 2027 to resume its own orbit around the Sun.

The Times of India reports the asteroid takes about 359 days to circle the Sun — slightly shorter than an Earth year — so its current stay is a brief interruption in a routine journey rather than the start of a permanent relationship.

According to The Times of India, orbital analysis shows the object has passed near Earth before, coming relatively close roughly once a decade, including a pass in 1965 that did not result in capture.

According to The Times of India, citing EarthSky, the object's next predicted approach in 2058 is also not expected to result in another temporary capture — a notable nuance for a rock that briefly earned the title of Earth's second natural satellite.

The Times of India also notes that 2026 QQ8's closest predicted distance during this visit is about 568,000 kilometres, roughly one-and-a-half times the average Earth–Moon distance, which is why it poses no impact threat: it is so small it would simply burn up in the atmosphere.

BBC Sky at Night Magazine adds that once it leaves Earth orbit, the object won't come this close again until 2058.

Hungarian astronomer Krisztián Sárneczky first spotted the faint object on 20 August 2026, and the Minor Planet Center initially suspected it was human-made space junk from an old rocket or satellite.

Follow-up observations with the University of Hawaii's 2.2-metre telescope and the Lowell Discovery Telescope resolved the question — The Times of India reports that measurements of how the object responded to solar radiation pressure ruled out an artificial origin.

On 29 October 2026 the Minor Planet Center classified it as a natural, temporarily captured object and it was officially designated a moon as 2026 QQ8.

The Times of India reports that a 2025 study in the journal Icarus suggested Earth could average around six lunar-origin mini-moons at any given time — fragments blasted off the Moon by asteroid impacts — typically staying for about nine months, though with considerable uncertainty.

Research presented at the 2026 Europlanet Science Congress, as reported by The Times of India, suggested the largest mini-moon present at any moment is typically only about 75 centimetres across, while a three-metre rock could remain captured for 10 to 20 years under the right conditions.

Previous temporary satellites include 2020 CD3 and 2024 PT5, and improving survey telescopes are making these small, faint, fast-moving visitors easier to catch.
