Key Facts

Overview

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

Dallas orbits the sun every 1,960 days (5.37 years), coming as close as 2.39 AU and reaching as far as 3.74 AU from the sun. Dallas is about 13.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Cleveland, Ohio.

No Close Approaches

Dallas's orbit is 1.40 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

Dallas's orbit is determined by observations dating back to March 26, 1973. It was last officially observed on June 21, 2023. The IAU Minor Planet Center records 2,796 observations used to determine its orbit.

Accessibility and Exploration

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