Whenthe OSIRIS-REx spacecraft swings by Earth on Sunday, it is expected to deliver a rare cosmic gift: a pristine sample collected from the near-Earth asteroid Bennu. If all goes according to
Asmall asteroid, only about 1 meter in diameter, entered the Earth’s atmosphere over northwestern France on Feb 13 at about 02:59 UTC. The asteroid, designated 2023 CX1, produced a bright fireball, which was witnessed from regions of England, France, Belgium, Germany, and the Netherlands.. Ground track of 2023 CX1:
Thepotentially hazardous asteroid 2023 FM is larger than a 40-story building and will zoom within 7.5 lunar distances from Earth on Thursday, April 6, according to NASA. The large asteroid 2023
Infact, a group of astronomers have been keeping close tabs on large, near-Earth objects — and have projected their movements over the next 1,000 years to determine whether any have a significant chance of veering off into our oasis in the solar system.

Timeline Comet and asteroid impacts. By David Chandler. 4 September 2006. This is the last panoramic mosaic of comet P/Shoemaker-Levy 9 taken on 17 May 1994 by the Hubble Space Telescope. The Thismeans the impactor that formed the Vredefort crater would have been larger than the asteroid that killed off the dinosaurs 66 million years ago, forming the Chicxulub crater. That impact had damaging effects globally, including greenhouse heating, widespread forest fires, acid rain, and destruction of the ozone layer, in addition to Sentryis a highly automated collision monitoring system that continually scans the most current asteroid catalog for possibilities of future impact with Earth over the next 100 Theseimpact zones show where scientists have found meteorites, or the impact craters of meteorites, some dating back as far as the year 2,300BC. The data is from the Meteocritical Society and Theclosest the asteroid is expected to travel to Earth is about 1.1 million miles (1.8 million kilometers), NASA's Eyes on Asteroids website notes. The space rock was first spotted in our skies
Shockedzircon crystals in melt rock from the ~250- to 300-kilometer-diameter Vredefort impact structure, the largest one on Earth, yielded a U-Pb age of 2023 ± 4 Ma. Zircon grains crystallized from Sudbury’s impact melt sheet produced a U-Pb age of 1850 ± 1 Ma. In a recent study, intensely shock-metamorphosed zircon grains recrystallized
Ascreenshot from the Asteroid Launcher impact simulator shows the fireball created by the impact of a 1-kilometer-wide asteroid striking New York City at an angle of 45 degrees while traveling at Watchon. This animation depicts the orbital trajectory of asteroid 99942 Apophis as it zooms safely past Earth on April 13, 2029. Earth’s gravity will slightly deflect the trajectory as the 1,100-foot-wide (340-meter-wide) near-Earth object comes within 20,000 miles (32,000 kilometers) of our planet’s surface. Thereare many asteroids and comets with orbits that come closer than twenty-eight million miles (forty-five million kilometers) to the orbit of the Earth. They are called near-Earth objects (NEOs). The NEOs are worlds of opportunity and danger for mankind. One may be one of the first destinations for the Multi-Purpose Crew Vehicle. Thisnew NASA map shows all 556 times an asteroids or meteors entered Earth's atmosphere since 1994 — and gives you an idea of just how regular these events are: The good news is that virtually lGI4XU.
