The International Astronomical Union's Minor Planet Center officially verified 2026 QQ8's trajectory after researchers used the Lowell Discovery Telescope and the University of Hawaii's 2.2-metre telescope to analyze solar radiation pressure on the body. Although it passes near Earth approximately once every decade, this specific visit is unique because other encounters do not involve orbital capture. The asteroid poses no threat to the planet, maintaining a safe distance of about 568,000 kilometres at its closest approach.

Earth has acquired a temporary companion in space, but it will not stay for long. A small space rock named 2026 QQ8 was pulled into Earth's gravitational grip in April 2026, remained unnoticed for months and was first spotted in August. Now confirmed as a natural object, the roughly 1–2-metre-wide asteroid is expected to remain temporarily bound to our planet until December before escaping and continuing its journey around the Sun in 2027.
The discovery was reported by the International Astronomical Union's Minor Planet Center on October 29, after astronomers had gathered enough observations to establish the object's identity and trajectory. Hungarian astronomer Krisztián Sárneczky first observed it on August 19–20, according to reports by Space.com. Initially, however, scientists were unsure whether the faint object was a natural space rock or human-made debris from an old rocket or satellite.
Follow-up observations helped resolve that uncertainty. Astronomers used the University of Hawaii's 2.2-metre telescope and the Lowell Discovery Telescope to study the object.
The additional measurements, including how it responded to solar radiation pressure, helped rule out an artificial origin. The…
Beijing is opening its orbital outpost to international partners for the first time under the Belt and Road Initiative framework. The selected payload specialist will conduct a short-term mission aboard the Shenzhou-24 flight before returning on another vessel. This historic milestone underscores deepening bilateral aerospace ties as China accelerates its broader ambitions for lunar exploration.
Located 1,600 light-years away in the constellation Virgo, star J1328−1450 was observed using the European Southern Observatory's Very Large Telescope in Chile. Unlike 21 previously identified debris-surrounded white dwarfs with solitary discs, this system features a novel dual configuration shaped by surviving embedded rocky bodies. The findings provide critical insight into the destructive gravitational forces that could reshape our own solar system after the sun collapses.
Astronomers analyzed early imaging covering just a fraction of the southern sky to detect an ultra-faint galaxy alongside an obscured star cluster. These observations demonstrate how upcoming full-sky mapping will systematically expose the Milky Way's missing satellite systems. Tracing these elusive cosmic structures will directly support ongoing research into how our galaxy assembled and help clarify the behavior of dark matter.
