‘Potentially Hazardous Asteroid’ The Size Of An Airplane To Pass By Earth On September 15


An aeroplane-sized asteroid is approaching Earth on Thursday, September 15, 2022. The asteroid, called 2020 PT4, has a diameter of 37 meters. It will make its closest approach to Earth at a distance of 71,90,000 kilometers on Thursday, according to NASA’s Jet Propulsion Laboratory. Asteroid 2020 PT4 is moving at a velocity of 10.85 kilometers per second, according to NASA’s Center for Near Earth Object Studies (CNEOS). Due to the distance at which the asteroid will make its closest approach to Earth, and its size, it has been classified a ‘Potentially Hazardous Asteroid’.

All About Asteroid 2020 PT4

The asteroid has an orbital period of 734 days or two years, which means it takes 734 days to orbit its host star.

It is an Apollo-class asteroid, a term used for an object whose orbit crosses that of Earth. The last time asteroid 2020 PT4 made a close approach to Earth was on September 8, 2020. The asteroid will make its next approach to Earth on September 28, 2024.
