Key Facts

Overview

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

Dannymeyer orbits the sun every 2,050 days (5.61 years), coming as close as 3.13 AU and reaching as far as 3.20 AU from the sun. Dannymeyer is about 31.6 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of New York.

The rotation of Dannymeyer has been observed. It completes a rotation on its axis every 28.13 hours.

No Close Approaches

Dannymeyer's orbit is 2.11 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

Dannymeyer's orbit is determined by observations dating back to Jan. 14, 1983. It was last officially observed on May 9, 2023. The IAU Minor Planet Center records 4,466 observations used to determine its orbit.

Accessibility and Exploration

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