Шаблон:Mp is a very small asteroid classified as a near-Earth object of the Earth-crossing Apollo group. When it was discovered by the Pan-STARRS 2 survey on 27 April 2020, the asteroid was initially calculated to have a 10% chance of impact with Earth before being ruled out by improved orbit determinations from additional observations.[1] Although there is now no risk of impact with Earth, it did make a close approach Шаблон:Convert from Earth on 28 April 2020, with a flyby speed of Шаблон:Convert relative to Earth.[2][3][4] The asteroid will not make any close encounters within Шаблон:Convert of Earth in the next 100 years.[2]
Observations by Kiso Observatory in Nagano, Japan show that the asteroid rotates extremely rapidly with a rotation period of 3 seconds, making it the fastest-rotating asteroid known Шаблон:As of.[5] No other near-Earth asteroid of similar size is known to have a rotation period shorter than 10 seconds, which could be attributed to the tangential component of the YORP effect accelerating their rotation far beyond this period.[5] The asteroid exhibits a very small light curve amplitude of 0.07 magnitudes, which either implies a nearly spherical shape or a pole-on rotation during observations.[5]
