Key Facts

Overview

19986 (1990 KD) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1990 KD as potentially hazardous because its orbit does not bring it close to Earth.

1990 KD orbits the sun every 1,480 days (4.05 years), coming as close as 1.89 AU and reaching as far as 3.19 AU from the sun. 1990 KD is about 7.5 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.

No Close Approaches

1990 KD's orbit is 0.88 AU from Earth's orbit at its closest point. This means that there is a very wide berth between this asteroid and Earth at all times.

Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.

Images and Observations

1990 KD's orbit is determined by observations dating back to May 19, 1990. It was last officially observed on June 28, 2023. The IAU Minor Planet Center records 1,736 observations used to determine its orbit.

Accessibility and Exploration

This asteroid is not considered a viable target for human exploration by the NHATS study.
