2017 KN27 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2017 KN27 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.
2017 KN27 orbits the sun every 467 days (1.28 years), coming as close as 0.76 AU and reaching as far as 1.60 AU from the sun. Based on its brightness and the way it reflects light, 2017 KN27 is probably between 0.022 to 0.049 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2017 KN27's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
2017 KN27 has 2 close approaches predicted in the coming decades:
|Date||Distance from Earth (km)||Velocity (km/s)|
|Nov. 21, 2020||22,650,101||20.504|
|Nov. 23, 2043||16,578,325||19.599|
2017 KN27's orbit is determined by observations dating back to May 25, 2017. It was last officially observed on June 2, 2017. The IAU Minor Planet Center records 76 observations used to determine its orbit.
