Key Facts

Overview

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

Schilowa orbits the sun every 2,040 days (5.59 years), coming as close as 2.60 AU and reaching as far as 3.69 AU from the sun. Schilowa is about 33.7 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of New York.

The rotation of Schilowa has been observed. It completes a rotation on its axis every 29.54 hours.

No Close Approaches

Schilowa's orbit is 1.60 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

Schilowa's orbit is determined by observations dating back to Oct. 24, 1905. It was last officially observed on Feb. 9, 2023. The IAU Minor Planet Center records 4,729 observations used to determine its orbit.

Accessibility and Exploration

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