Just earlier this week, we covered the news of giant asteroid, named 2019 OU1, hurtling past Earth. Now another asteroid, ‘2018 PN22’ has been spotted which will approach towards Earth on August 17 at 7:16 PM (ST). The 2018 PN22 asteroids hasn’t been tagged as a potentially hazardous asteroid and doesn’t indicate any chances of future collision.
According to spacereference.org, 2018 PN22 is a very small asteroid whose orbit could bring it in close proximity to Earth. 2018 PN22 is sized somewhere between 0.055 to 0.250 kilometers in diameter, which makes it a small to average asteroid. To put into perspective the size of this asteroid, it can be compared to a school bus or something even smaller. 2018 PN22 has also been classified as a “Near Earth Asteroid” by NASA JPL because of its orbit’s proximity to Earth. 2018 PN22 orbits the sun every 364 days (1.00 years), where it can come as close as 0.96 AU and reach as far as 1.04 AU from the sun.
There are several dozen asteroids, ranging in the size of 6-12 m that passes by Earth every year, however, only a couple of these manage to get detected. Also, about 30 small asteroids, ranging few meters in size, collide with Earth every year. But, they don’t cause any damage and only their fragments manage to make it to the surface as meteorites.
