PARIS (ESA PR) — Asteroid 2006 QV89, a small object 20 to 50 metres in diameter, was in the news lately because of a very small, 1-in-7000 chance of impact with Earth on 9 September 2019.
In the first known case of ruling out an asteroid impact through a
‘non-detection’, ESA and the European Southern Observatory have
concluded that asteroid 2006 QV89 is not on a collision course this year – and the chance of any future impact is extremely remote.
PASADENA, Calif. (NASA PR) — Nearly all asteroids are so far away and so small that the astronomical community only knows them as moving points of light. The rare exceptions are asteroids that have been visited by spacecraft, a small number of large asteroids resolved by NASA’s Hubble Space Telescope or large ground-based telescopes, or those that have come close enough for radar imaging.
