Key Facts

Overview

Dvorak is a mid-sized asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified Dvorak as potentially hazardous because its orbit does not bring it close to Earth.

Dvorak orbits the sun every 1,280 days (3.50 years), coming as close as 1.59 AU and reaching as far as 3.03 AU from the sun. Based on its brightness and the way it reflects light, Dvorak is probably between 6.927 to 15.490 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.

The rotation of Dvorak has been observed. It completes a rotation on its axis every 4.41 hours.

No Close Approaches

Dvorak's orbit is 0.69 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

Dvorak's orbit is determined by observations dating back to Feb. 19, 1974. It was last officially observed on June 30, 2023. The IAU Minor Planet Center records 3,027 observations used to determine its orbit.

Accessibility and Exploration

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