Key Facts

Overview

14580 (1998 QW101) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1998 QW101 as potentially hazardous because its orbit does not bring it close to Earth.

1998 QW101 orbits the sun every 1,490 days (4.08 years), coming as close as 2.08 AU and reaching as far as 3.04 AU from the sun. 1998 QW101 is about 3.7 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.

No Close Approaches

1998 QW101's orbit is 1.13 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

1998 QW101's orbit is determined by observations dating back to Oct. 12, 1990. It was last officially observed on Aug. 26, 2022. The IAU Minor Planet Center records 1,325 observations used to determine its orbit.

Accessibility and Exploration

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