Key Facts

Overview

11048 (1990 QZ5) is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1990 QZ5 as potentially hazardous because its orbit does not bring it close to Earth.

1990 QZ5 orbits the sun every 1,760 days (4.82 years), coming as close as 2.41 AU and reaching as far as 3.31 AU from the sun. 1990 QZ5 is about 14.9 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Baltimore.

The rotation of 1990 QZ5 has been observed. It completes a rotation on its axis every 5.98 hours.

No Close Approaches

1990 QZ5's orbit is 1.45 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

1990 QZ5's orbit is determined by observations dating back to Dec. 19, 1981. It was last officially observed on June 28, 2023. The IAU Minor Planet Center records 3,163 observations used to determine its orbit.

Accessibility and Exploration

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