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 ]
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.
In samples NASA brought back from the asteroid Bennu, scientists have discovered of organic compounds, including key building blocks of life like amino acids.
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 ...
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 ]
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 ...
