Lomia

Key Facts

• Categorized as a Main-belt Asteroid
• Comparable in size to the U.S. state of Maryland (208.97 km diameter)
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

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

Lomia orbits the sun every 1,890 days (5.17 years), coming as close as 2.92 AU and reaching as far as 3.06 AU from the sun. Lomia is about 209.0 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Maryland.

The rotation of Lomia has been observed. It completes a rotation on its axis every 9.13 hours.

Lomia's spectral type XC (Tholen) / X (SMASSII) indicates that it is likely to contain iron, nickel, and cobalt.

No Close Approaches

Lomia's orbit is 1.93 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

Lomia's orbit is determined by observations dating back to Aug. 16, 1876. It was last officially observed on May 7, 2023. The IAU Minor Planet Center records 5,709 observations used to determine its orbit.
