Overview
2017 KN34 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2017 KN34 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2017 KN34 orbits the sun every 747 days (2.05 years), coming as close as 0.42 AU and reaching as far as 2.81 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2017 KN34 is probably between 0.308 to 0.689 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to the U.S. Capitol building.
Close Approaches
2017 KN34'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 KN34 has 4 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| April 23, 2060 | 1,042,649 | 34.944 |
| April 25, 2105 | 4,109,866 | 34.349 |
| April 23, 2148 | 3,899,986 | 35.537 |
| April 25, 2193 | 3,671,964 | 34.384 |
