Key Facts

Overview

68031 (2000 YK29) is a small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2000 YK29 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.

2000 YK29 orbits the sun every 590 days (1.62 years), coming as close as 1.20 AU and reaching as far as 1.55 AU from the sun. Based on its brightness and the way it reflects light, 2000 YK29 is probably between 0.638 to 1.426 kilometers in diameter, making it small in absolute terms, but larger than ~97% of asteroids, very roughly comparable in size to the Golden Gate Bridge.

The rotation of 2000 YK29 has been observed. It completes a rotation on its axis every 2.55 days.

No Close Approaches

2000 YK29's orbit is 0.23 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.

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

Images and Observations

2000 YK29's orbit is determined by observations dating back to March 22, 1993. It was last officially observed on July 27, 2019. The IAU Minor Planet Center records 581 observations used to determine its orbit.

Accessibility and Exploration

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