Mcalanis

Key Facts

• Categorized as a Main-belt Asteroid
• Comparable in size to Mount Everest (2.33 km diameter)
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

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

Mcalanis orbits the sun every 1,240 days (3.39 years), coming as close as 2.22 AU and reaching as far as 2.29 AU from the sun. Mcalanis is about 2.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to Mount Everest.

No Close Approaches

Mcalanis's orbit is 1.22 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

Mcalanis's orbit is determined by observations dating back to Nov. 30, 1995. It was last officially observed on April 13, 2023. The IAU Minor Planet Center records 3,227 observations used to determine its orbit.

Accessibility and Exploration

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