Overview

1998 KY26 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1998 KY26 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.

1998 KY26 orbits the sun every 500 days (1.37 years), coming as close as 0.98 AU and reaching as far as 1.48 AU from the sun. 1998 KY26 is about 0.0 kilometers in diameter, making it a small to average asteroid, comparable in size to a school bus or smaller.

The rotation of 1998 KY26 has been observed. It completes a rotation on its axis every 0.18 hours.

Close Approaches

1998 KY26's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

1998 KY26 has 10 close approaches predicted in the coming decades:

Images and Observations

1998 KY26's orbit is determined by observations dating back to May 31, 1998. It was last officially observed on Dec. 12, 2020. The IAU Minor Planet Center records 65 observations used to determine its orbit.

Accessibility and Exploration

1998 KY26 can be reached with a journey of 442 days. This trajectory would require a delta-v of 7.845 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 99,448 potential trajectories and launch windows to this asteroid.
