Key Facts

Overview

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

Algoa orbits the sun every 1,390 days (3.81 years), coming as close as 2.25 AU and reaching as far as 2.62 AU from the sun. Based on its brightness and the way it reflects light, Algoa is probably between 12.547 to 28.057 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the city of Philadelphia.

The rotation of Algoa has been observed. It completes a rotation on its axis every 2.77 hours.

No Close Approaches

Algoa's orbit is 1.24 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

Algoa's orbit is determined by observations dating back to June 12, 1936. It was last officially observed on July 4, 2023. The IAU Minor Planet Center records 4,804 observations used to determine its orbit.

Accessibility and Exploration

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