As per the Center for Near-Earth Object Studies (CNEOS), an asteroid, given the designation of Asteroid 2023 TW6, is on its way toward Earth and could pass the planet at a distance of approximately 7.3 million kilometers. Know all the details about the asteroid’s close approach. ## Asteroid 2023 TW6: Speed, size, and more This Near-Earth Asteroid (NEA) is expected to make its closest approach to the planet at a speed of about 88007 kilometers per hour which is much faster even a space shuttle! It is important to note that while it has been termed as a Near-Earth Asteroid due to its close distance of passing, it is not expected to actually impact the planet. 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. Also read click here. ## How big is the asteroid? According to NASA, Asteroid 2023 TW6 is approximately 280 feet wide, making it almost as big as a building! It is almost 6 times larger than the Chelyabinsk asteroid which caused destruction in 2013. Despite its size, the asteroid has not been termed as a Potentially Hazardous Asteroid. Only celestial objects larger than 492 feet that pass Earth at a distance closer than 7.5 million kilometers are designated so. Shockingly, this asteroid made its first-ever close approach to Earth more than 100 years ago! It passed by Earth on December 10, 1905, at a distance of about 63 million kilometers. After today, Asteroid 2023 TW6 will pass by Earth on October 20, 2030, at a distance of 24 million kilometers, according to NASA’s Jet Propulsion Laboratory. ## Tech used in asteroid hunting To discover, monitor and study asteroids in space, NASA has several space telescopes and ground-based observatories in place. These include the famous Hubble Space Telescope and the new James Webb Space Telescope. Moreover, spacecraft such as Dawn, OSIRIS-REx, and Hayabusa2 have also helped in studying these ancient space rocks.
