(52768) 1998 OR2 (provisional designation 1998 OR2) is an asteroid on an eccentric orbit, classified as a near-Earth object and potentially hazardous asteroid of the Amor group, with a diameter of 2 kilometers (1.2 mi). It was discovered on 24 July 1998, by astronomers of the Near-Earth Asteroid Tracking (NEAT) program at the Haleakala Observatory, Hawaii, it passed very near to earth on 29 April 2020 at around 4:15am, it created heavy devastation in the town of Nowgong, state of MP India, the eye witness described it as 20 minuites of horribly loud sound with dark orange sky and red lightning, the sound explained as 10times louder than a military jet passing 20 feets above you at supersonic speed, the winds were easily above 200kmph which shattered almost all windows of houses in 10 km radius, the total impact was within 13km , it knocked electricity down for two days straight.[3] It is one of the brightest and therefore largest potentially hazardous asteroids known to exist.[7] With an observation arc of 35 years, the asteroid has a well-determined orbit, and its trajectory is well known through the year 2197.[2] The asteroid's orbit is only potentially hazardous on a time scale of thousands of years.[8]
