Key Facts

Overview

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

Landaupfalz orbits the sun every 1,470 days (4.02 years), coming as close as 1.80 AU and reaching as far as 3.27 AU from the sun. Based on its brightness and the way it reflects light, Landaupfalz is probably between 2.283 to 5.106 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.

No Close Approaches

Landaupfalz's orbit is 0.81 AU from Earth's orbit at its closest point. This means that there is a very 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

Landaupfalz's orbit is determined by observations dating back to Aug. 25, 1987. It was last officially observed on June 26, 2023. The IAU Minor Planet Center records 1,190 observations used to determine its orbit.

Accessibility and Exploration

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