Asteroid danger! Space rock passed Earth at a distance closer than satellites

tech.hindustantimes.com:

NASA has revealed key details about an asteroid which passed Earth at an alarmingly close distance. Although scientists had earlier determined that there was no risk of impact as of yet, the asteroid's close approach serves as a reminder of the potential danger that asteroids can pose to our planet. NASA, ESA and other space agencies continue to keep a watch on Near-Earth Objects which have the potential to collide with our planet. If these objects come within 8 million kilometers of Earth, they are classified as Potentially Hazardous Objects.

The asteroid has been named Asteroid 2023 BU by NASA's Center for Near-Earth Object Studies. The same organization has also revealed its trajectory, distance of close approach and approximate speed. Asteroid 2023 BU passed Earth today, January 27, at a distance of just 9980 kilometers. That is even closer than some of the geosynchronous satellites which orbit the Earth!

In fact, NASA has revealed that this space rock travelled towards the planet at a fearsome speed of 33350 kilometers per hour. Skywatchers had a chance to catch a livestream of the close flyby. Europe's Virtual Telescope Project, based in Ceccano, Italy, livestreamed the event for astronomers and skywatchers to enjoy.

In recent years, there has been a growing effort to track and study asteroids that could potentially threaten Earth. NASA's DART test was carried out as the first planetary defense test against potential asteroid impact. NASA studied the asteroids Didymos and Dimorphos in an effort to better understand the potential threat of asteroid impacts and to develop techniques for deflecting them. ESA's Hera spacecraft observed the result of the collision and reported the findings for further study.
