Asteroids often make close approaches to Earth, but did you know that one of them hit the planet this year? NASA revealed that on February 15, a 1000-pound, 2 feet wide space rock turned into an atmospheric fireball and broke into pieces about 21 miles above Earth's surface and was found near McAllen, Texas. Law enforcement agencies in the McAllen region received several calls from residents who reported hearing a loud explosion. According to NASA, the space rock was travelling at about 43000 kilometers per hour and it had an energy of about 8 tons of TNT.
While not expected to hit Earth, NASA has warned that another space rock will pass Earth at quite a close ditance today, August 23. Know all the details.
Anasteroid, given the designation of Asteroid 2023 QW, is on its way towards Earth and could make its closest approach to the planet today, August 23. NASA revealed these details after tracking the asteroid's orbit using its various satellites and space and ground-based telescopes. As per the details, Asteroid 2023 QW is expected to make its closest approach to the planet at a distance of just 1.6 million kilometers, and at a speed of 58848 kilometers per hour.
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.
According to NASA, Asteroid 2023 QW has not been classified as a Potentially Hazardous Object due to its relatively small size. Only objects larger than 492 feet in diameter are deemed hazardous. In comparison, Asteroid 2023 QW is just 71 feet wide, making it almost as big as a small aircraft.
