While the finding of 2022 AP7 may bring to mind visions of the asteroid Armageddon depicted in the film Dont Look Up, the study also offers reassurance. To change a bigger asteroid's path, we can either crash something into it at high speeds or detonate a nuclear warhead nearby. In the case of 2022 AE1, observations after the full Moon had waned provided the data needed to show that the risk level calculated from early observations was wrong. #C8FF042Predicted time of atmospheric entry is 8:26 UTC, over the great lakes. This article was originally published by Universe Today. Tate said an approach like Dart might not be suitable for 2022 AP7, given the size of the asteroid, but there were other possible methods. Its reckoned that an asteroid as big as that coming as close to Earth as Apophis will is a one-in-a-thousand-years event. The asteroid was discovered by the four-metre Blanco telescope at the Cerro Tololo observatory in Chile. Given the huge size of Didymos and its moon, ground-based telescopes will be able to detect the asteroid very soon. Initial observations of an asteroid dubbed '2022 AE1' showed a potential Earth impact on 4 July 2023 - not enough time to attempt deflection and large enough to do real damage to a local area should it strike. And with the network of observatories around the world that are focused on planetary defense i.e., searching the skies for incoming asteroids and comets multiple observations and quickly rule out any space rocks that aren't a threat. As it was removed from our risk list, we didn't need to follow it anymore time to move onto the next.". A 1,200-pound . In Depth.

Impact should have been around Brantford, Ontario. The primary objective of DART, which stands for Double Asteroid Redirection Test, was to test our ability to alter the asteroid's trajectory as it orbits its larger companion asteroid, Didymos. The spacecraft is . That year has come and gone and, mostly due to a lack of financial resources, only 40% of those objects have been mapped. Apophis isnt going to strike our planet on April 13, 2029, but scientists think that the effect on it of the close pass could be to alter its trajectoryand dangerously so. New study of NASA's DART mission suggests that altering the course of an asteroid could work to protect Earth. Near-Earth objects include asteroids and comets whose orbits will bring them within 120 million miles (193 million kilometers) of the Sun. Thats about 23,000 miles/37,000 kilometers from Earths surface. NASA Center for Near Earth Object Studies page on the asteroid.
