Flammario

Key Facts

• Categorized as a Main-belt Asteroid
• Comparable in size to the U.S. state of Delaware (100.77 km diameter)
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

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

Flammario orbits the sun every 1,660 days (4.54 years), coming as close as 1.96 AU and reaching as far as 3.52 AU from the sun. Flammario is about 100.8 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Delaware.

The rotation of Flammario has been observed. It completes a rotation on its axis every 12.16 hours.

Flammario's spectral type F (Tholen) / B (SMASSII) indicates that it is likely to contain hydrogen, nitrogen, ammonia, and iron.

No Close Approaches

Flammario's orbit is 1.03 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

Flammario's orbit is determined by observations dating back to May 18, 1925. It was last officially observed on May 15, 2023. The IAU Minor Planet Center records 3,759 observations used to determine its orbit.
