Lucubratio

Key Facts

• Categorized as a Outer Main-belt Asteroid
• Comparable in size to the city of Indianapolis (24.43 km diameter)
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

Lucubratio is a large asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified Lucubratio as potentially hazardous because its orbit does not bring it close to Earth.

Lucubratio orbits the sun every 2,090 days (5.72 years), coming as close as 2.45 AU and reaching as far as 3.96 AU from the sun. Lucubratio is about 24.4 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Indianapolis.

The rotation of Lucubratio has been observed. It completes a rotation on its axis every 12.09 hours.

No Close Approaches

Lucubratio's orbit is 1.53 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

Lucubratio's orbit is determined by observations dating back to March 27, 1973. It was last officially observed on April 22, 2023. The IAU Minor Planet Center records 2,963 observations used to determine its orbit.
