Znanstvenici su prvi put otkrili vodu na površini asteroida što sugerira da voda nije nastala na Zemlji

Proučavali su četiri asteroida i utvrdili da dva emitiraju valnu duljinu koja ukazuje na prisutnost molekula vode

Image shows: This view from NASA’s Scout system shows the deflection of asteroid 2023 BU’s trajectory – in red – caused by Earth’s gravity. The orbit of geosynchronous satellites is shown in green, and the orbit of the Moon is depicted by the gray oval. Asteroid 2023 BU is about the size of a box truck and is predicted to make one of the closest approaches by a near-Earth object ever recorded. The asteroid was discovered by amateur astronomer Gennadiy Borisov, discoverer of the interstellar comet 2I/Borisov, from his MARGO observatory in Nauchnyi, Crimea, on Saturday, Jan. 21. Additional observations were reported to the Minor Planet Center (MPC) – the internationally recognized clearinghouse for the position measurements of small celestial bodies – and the data was then automatically posted to the Near-Earth Object Confirmation Page. After sufficient observations were collected, the MPC announced the discovery. Within three days, a number of observatories around the world had made dozens of observations, helping astronomers better refine 2023 BU’s orbit. NASA’s Scout impact hazard assessment system, which is maintained by the Center for Near Earth Object Studies (CNEOS) at the agency’s Jet Propulsion Laboratory in Southern California, analyzed the data from the MPC’s confirmation page and quickly predicted the near miss. CNEOS calculates every known near-Earth asteroid orbit to provide assessments of potential impact hazards in support of NASA’s Planetary Defense Coordination Office (PDCO). While any asteroid in Earth’s proximity will experience a change in trajectory due to our planet’s gravity, 2023 BU will come so close that its path around the Sun is expected to be significantly altered. Before encountering Earth, the asteroid’s orbit around the Sun was roughly circular, approximating Earth’s orbit, taking 359 days to complete its orbit about the Sun. After its encounter, the asteroid’s orbit will be more elongated, moving it out to about halfway between Earth’s and Mars’ orbits at its farthest point from the Sun. The asteroid will then complete one orbit every 425 days. -PICTURED: Truck-Sized Asteroid -LOCATION: United States United States -DATE: 26 Jan 2023 -CREDIT: NASA/JPL-Caltech/Cover Images/INSTARimages.com,Image: 752024714, License: Rights-managed, Restrictions: , Model Release: no, Pictured: Truck-Sized Asteroid

Zemlji će prići na udaljenost od oko dva milijuna kilometara

This artist's rendition released 20 April, 2005 by NASA shows a massive asteroid belt in orbit around a star the same age and size as our Sun. Evidence for this possible belt was discovered by NASA's Spitzer Space Telescope when it spotted warm dust around the star, presumably from asteroids smashing together. The view starts from outside the belt, where planets like the one shown here might possibly reside, then moves into to the dusty belt itself. A collision between two asteroids is depicted near the end of the movie. Collisions like this replenish the dust in the asteroid belt, making it detectable to Spitzer. The alien belt circles a faint, nearby star called HD 69830 located 41 light-years away in the constellation Puppis. Compared to our own solar system's asteroid belt, this one is larger and closer to its star - it is 25 times as massive, and lies just inside an orbit equivalent to that of Venus. Our asteroid belt circles between the orbits of Mars and Jupiter. AFP PHOTO/HO/NASA

This artist's illustration obtained from NASA on December 21, 2018 shows the New Horizons spacecraft encountering 2014 MU69 – nicknamed “Ultima Thule” – a Kuiper Belt object that orbits one billion miles beyond Pluto. - A NASA spaceship is zooming toward the farthest, and quite possibly the oldest, cosmic body ever photographed by humankind -- a tiny, distant world called Ultima Thule -- in the hopes of learning more about how planets took shape. The US space agency will ring in the New Year with a live online broadcast to mark the historic flyby of the mysterious object located about four billion miles (6.4 billion kilometers) away in a dark and frigid region of space known as the Kuiper Belt.
