Key Facts


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

Barcelona orbits the sun every 1,560 days (4.27 years), coming as close as 2.21 AU and reaching as far as 3.06 AU from the sun. Barcelona is about 25.6 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Indianapolis.

The rotation of Barcelona has been observed. It completes a rotation on its axis every 7.36 hours.

Barcelona's spectral type S (Tholen) / Sq (SMASSII) indicates that it is likely to contain and .

No Close Approaches

Barcelona'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

Barcelona's orbit is determined by observations dating back to Feb. 23, 1921. It was last officially observed on March 14, 2023. The IAU Minor Planet Center records 3,073 observations used to determine its orbit.

Accessibility and Exploration

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