Key Facts

Overview

5611 (1943 DL) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1943 DL as potentially hazardous because its orbit does not bring it close to Earth.

1943 DL orbits the sun every 1,530 days (4.19 years), coming as close as 2.25 AU and reaching as far as 2.94 AU from the sun. 1943 DL is about 9.4 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.

The rotation of 1943 DL has been observed. It completes a rotation on its axis every 325.67 hours.

No Close Approaches

1943 DL's orbit is 1.29 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

1943 DL's orbit is determined by observations dating back to Feb. 26, 1943. It was last officially observed on July 5, 2023. The IAU Minor Planet Center records 3,748 observations used to determine its orbit.

Accessibility and Exploration

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