Key Facts

Overview

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

Vindobona orbits the sun every 1,830 days (5.01 years), coming as close as 2.48 AU and reaching as far as 3.37 AU from the sun. Vindobona is about 73.5 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Delaware.

The rotation of Vindobona has been observed. It completes a rotation on its axis every 14.25 days.

No Close Approaches

Vindobona's orbit is 1.47 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

Vindobona's orbit is determined by observations dating back to Jan. 22, 1885. It was last officially observed on June 13, 2020. The IAU Minor Planet Center records 2,799 observations used to determine its orbit.

Accessibility and Exploration

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