Key Facts

Overview

Bowell is a large asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified Bowell as potentially hazardous because its orbit does not bring it close to Earth.

Bowell orbits the sun every 2,870 days (7.86 years), coming as close as 3.59 AU and reaching as far as 4.31 AU from the sun. Bowell is about 48.4 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Rhode Island.

The rotation of Bowell has been observed. It completes a rotation on its axis every 4.99 hours.

Bowell's spectral type D (Tholen) / D (SMASSII) indicates that it is likely to contain .

No Close Approaches

Bowell's orbit is 2.59 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

Bowell's orbit is determined by observations dating back to Jan. 15, 1955. It was last officially observed on July 5, 2023. The IAU Minor Planet Center records 3,766 observations used to determine its orbit.

Accessibility and Exploration

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