The asteroid with the greatest chance of impacting Earth in 2025 is 2009 VA (6-meters in diameter) with less than a 1-day observation arc. [8] It has a 1:48,000 chance of impact on 06 November 2023, but is expected to be around 0.3 AU (45 million km ) from Earth on that date with uncertainty region of ± 900 million km. [ 10 ]
An asteroid nearly the size of a football field now has roughly a 0.004% chance of hitting Earth in about eight years, NASA says — with the space agency saying it "no longer poses a significant ...
A list of known near-Earth asteroid close approaches less than 1 lunar distance (0.0025696 AU (384,410 km; 238,860 mi)) from Earth in 2017, based on the close approach database of the Center for Near-Earth Object Studies (CNEOS). [1] For reference, the radius of Earth is approximately 0.0000426 AU (6,370 km; 3,960 mi) or 0.0166 lunar distances.
NASA’s OSIRIS-REx spacecraft, which launched in 2016, scooped up bits of dust, soil and rocks from the asteroid Bennu and then brought them to Earth in 2023. The 4.5-billion-year-old asteroid is ...
NASA's groundbreaking mission to an asteroid A mission called OSIRIS-REx landed on an asteroid named Bennu in 2020, jammed its arm into the rock's surface, and scooped up a heaping sample of grit ...
The SAO/NASA Astrophysics Data System (ADS) is a digital library portal for researchers on astronomy and physics, operated for NASA by the Smithsonian Astrophysical Observatory. ADS maintains three bibliographic collections containing over 15 million records, including all arXiv e-prints. [ 1 ]
