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 ]
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 ]
In samples NASA brought back from the asteroid Bennu, scientists have discovered of organic compounds, including key building blocks of life like amino acids.
Landed; returned dust samples to Earth in 2010 - first sample return mission from asteroid; smallest asteroid visited by a spacecraft, first asteroid visited by a non-NASA spacecraft. 2867 Šteins: 4.6: 1969 Rosetta: 2008 800 302 Flyby; first asteroid visited by the ESA. 21 Lutetia: 120 × 100 × 75 (100 km) 1852 Rosetta: 2010 3,162: 64.9
Watch live as a Nasa spacecraft returns to Earth with the largest asteroid sample in history on Sunday 24 September. After a seven-year, four-billion-mile journey across space, the ambitious NASA ...
An analysis of material from Bennu that NASA researchers had harvested last fall already revealed the samples from the asteroid contained abundant water in the form of hydrated clay minerals as ...
Dinkinesh, the name borrowed from an Ethiopian word for the Lucy fossil, was the first flyby target of NASA's Lucy mission, which approached 425 km (264 mi) from the asteroid on 1 November 2023. [9] During the flyby, the Lucy spacecraft discovered that Dinkinesh has a contact-binary natural satellite , named Selam, which is 220 meters (720 ft ...
