Key Facts

Overview

7477 (1993 LC) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1993 LC as potentially hazardous because its orbit does not bring it close to Earth.

1993 LC orbits the sun every 1,560 days (4.27 years), coming as close as 2.28 AU and reaching as far as 2.98 AU from the sun. 1993 LC is about 6.8 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.

The rotation of 1993 LC has been observed. It completes a rotation on its axis every 74.24 hours.

No Close Approaches

1993 LC's orbit is 1.27 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

1993 LC's orbit is determined by observations dating back to July 7, 1989. It was last officially observed on July 1, 2023. The IAU Minor Planet Center records 3,047 observations used to determine its orbit.
