Key Facts

Overview

Dziewanna is a dwarf planet whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified Dziewanna as potentially hazardous because its orbit does not bring it close to Earth.

Dziewanna orbits the sun every 209,000 days (572.21 years), coming as close as 32.46 AU and reaching as far as 105.24 AU from the sun. Based on its brightness and the way it reflects light, Dziewanna is probably between 404.162 to 903.733 kilometers in diameter, making it one of the largest objects, very roughly comparable in size to Great Britain.

The rotation of Dziewanna has been observed. It completes a rotation on its axis every 7.07 hours.

No Close Approaches

Dziewanna's orbit is 31.60 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

Dziewanna's orbit is determined by observations dating back to March 15, 2002. It was last officially observed on June 18, 2023. The IAU Minor Planet Center records 225 observations used to determine its orbit.

Accessibility and Exploration

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