To minimize the uncertainty and counter the potential threat posed by asteroids that come close to Earth, space agencies like NASA, ESA, and others use advanced technologies like ground and space-based telescopes to keep an eye on these Near-Earth Objects. Although an asteroid isn't expected to hit Earth in the next 100 years, according to Dr. Davide Farnocchia of NASA's Center for Near Earth Object Studies (CNEOS), approximately 3,000 new NEOs are discovered annually, which makes continuous monitoring and trajectory prediction of these space rocks crucial.
NASA has now revealed details about an asteroid that is expected to make its closest approach to Earth today.
According to the data published by CNEOS, an asteroid designated as Asteroid 2023 JZ4 is approaching Earth at a ferocious speed and is expected to make its closest approach to the planet today, May 29. How fast is it going? Well, NASA has revealed that this space rock is currently travelling towards Earth at 57876 kilometers per hour. It will come as close as 2.3 million kilometers.
What's concerning about this asteroid is its size. NASA estimates it to be around 100 feet wide, which makes it almost as big as an aircraft! It belongs to the Apollo group of Near-Earth Asteroids, which are Earth-crossing space rocks with semi-major axes larger than Earth's. These asteroids are named after the humongous 1862 Apollo asteroid, discovered by German astronomer Karl Reinmuth in the 1930s.
Thanks to NASA technology like telescopes and other spacecraft, it has been discovered that one asteroid that the space agency is studying up close, called Bennu, has a 1/2700 chance of impacting Earth between 2175 and 2195. In fact, the OSIRIS-REx spacecraft has been sent on a mission -
