Amfortas

Key Facts

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

Overview

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

Amfortas orbits the sun every 1,290 days (3.53 years), coming as close as 1.97 AU and reaching as far as 2.66 AU from the sun. Based on its brightness and the way it reflects light, Amfortas is probably between 2.720 to 6.082 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the island of Manhattan.

The rotation of Amfortas has been observed. It completes a rotation on its axis every 3.85 hours.

No Close Approaches

Amfortas's orbit is 0.97 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

Amfortas's orbit is determined by observations dating back to Oct. 7, 1977. It was last officially observed on June 30, 2023. The IAU Minor Planet Center records 2,184 observations used to determine its orbit.

Accessibility and Exploration

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