The Minor Planet Center has confirmed that Earth’s gravitational field has temporarily trapped a brand-new “mini-moon,” designated as asteroid 2026 QQ8. Planetary scientists revealed that the small space rock entered our planet’s cosmic vicinity via the Hill sphere—the region where Earth’s gravity overrides the Sun’s pull—executing a complex loop around us. While measuring only a few feet in diameter and presenting zero collision risk, this temporary companion offers geophysicists an invaluable, close-up opportunity to study the primitive material composition of near-Earth objects before it escapes back into space at the end of the year.
