Key Facts

Overview

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

Stockholm orbits the sun every 2,010 days (5.50 years), coming as close as 2.48 AU and reaching as far as 3.75 AU from the sun. Stockholm is about 9.6 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.

The rotation of Stockholm has been observed. It completes a rotation on its axis every 3.76 hours.

No Close Approaches

Stockholm's orbit is 1.50 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

Stockholm's orbit is determined by observations dating back to Jan. 22, 1993. It was last officially observed on June 18, 2023. The IAU Minor Planet Center records 2,070 observations used to determine its orbit.

Accessibility and Exploration

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