Stromboli is a large asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified Stromboli as potentially hazardous because its orbit does not bring it close to Earth.
Stromboli orbits the sun every 2,920 days (7.99 years), coming as close as 3.34 AU and reaching as far as 4.66 AU from the sun. Stromboli is about 16.8 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Philadelphia.
The rotation of Stromboli has been observed. It completes a rotation on its axis every 15.96 hours.
Stromboli's orbit is 2.35 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.
Stromboli's orbit is determined by observations dating back to Sept. 24, 1960. It was last officially observed on June 29, 2023. The IAU Minor Planet Center records 2,081 observations used to determine its orbit.
