Prokofeana

Key Facts

• Categorized as a Mars-crossing Asteroid
• Comparable in size to the island of Manhattan
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

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

Prokofeana orbits the sun every 1,500 days (4.11 years), coming as close as 1.44 AU and reaching as far as 3.70 AU from the sun. Based on its brightness and the way it reflects light, Prokofeana is probably between 2.358 to 5.273 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the island of Manhattan.

The rotation of Prokofeana has been observed. It completes a rotation on its axis every 6.54 hours.

No Close Approaches

Prokofeana's orbit is 0.45 AU from Earth's orbit at its closest point. This means that there is a 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

Prokofeana's orbit is determined by observations dating back to Aug. 11, 1953. It was last officially observed on June 9, 2023. The IAU Minor Planet Center records 1,114 observations used to determine its orbit.

Accessibility and Exploration

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