Key Facts


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

Liriope orbits the sun every 2,400 days (6.57 years), coming as close as 3.25 AU and reaching as far as 3.76 AU from the sun. Liriope is about 88.8 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Delaware.

The rotation of Liriope has been observed. It completes a rotation on its axis every 11.01 hours.

Liriope's spectral type C (Tholen) / Cg (SMASSII) indicates that it is likely to contain water, iron, nickel, cobalt, nitrogen, and ammonia.

No Close Approaches

Liriope's orbit is 2.27 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

Liriope's orbit is determined by observations dating back to Nov. 5, 1907. It was last officially observed on July 24, 2021. The IAU Minor Planet Center records 3,793 observations used to determine its orbit.

Accessibility and Exploration

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