2014 KA91 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2014 KA91 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.
2014 KA91 orbits the sun every 515 days (1.41 years), coming as close as 0.91 AU and reaching as far as 1.61 AU from the sun. Based on its brightness and the way it reflects light, 2014 KA91 is probably between 0.014 to 0.062 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
The rotation of 2014 KA91 has been observed. It completes a rotation on its axis every 0.12 hours.
2014 KA91's orbit is 0.02 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.
2014 KA91 has 3 close approaches predicted in the coming decades:
|Date||Distance from Earth (km)||Velocity (km/s)|
|Oct. 13, 2021||24,288,249||5.754|
|July 27, 2076||25,694,172||6.482|
|Oct. 16, 2145||20,978,332||6.691|
2014 KA91's orbit is determined by observations dating back to May 30, 2014. It was last officially observed on June 9, 2014. The IAU Minor Planet Center records 34 observations used to determine its orbit.
2014 KA91 can be reached with a journey of 362 days. This trajectory would require a delta-v of 11.657 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 37 potential trajectories and launch windows to this asteroid.
