Key Facts

Overview

16003 (1999 BX2) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1999 BX2 as potentially hazardous because its orbit does not bring it close to Earth.

1999 BX2 orbits the sun every 2,060 days (5.64 years), coming as close as 2.74 AU and reaching as far as 3.60 AU from the sun. 1999 BX2 is about 6.6 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.

The rotation of 1999 BX2 has been observed. It completes a rotation on its axis every 19.79 hours.

No Close Approaches

1999 BX2's orbit is 1.75 AU from Earth's orbit at its closest point. This means that there is an extremely 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

1999 BX2's orbit is determined by observations dating back to March 18, 1988. It was last officially observed on April 29, 2023. The IAU Minor Planet Center records 2,333 observations used to determine its orbit.

Accessibility and Exploration

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