Key Facts

Overview

Comet 255P/Levy is an object whose orbit features a relatively short period, low inclination, and is controlled by Jupiter's gravitational effects. NASA JPL has classified 255P/Levy as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

255P/Levy orbits the sun every 1,920 days (5.26 years), coming as close as 0.99 AU and reaching as far as 5.06 AU from the sun.

Close Approaches

255P/Levy's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

255P/Levy has 3 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
Dec. 31, 2117 13,582,281 11.204
Jan. 2, 2149 16,167,561 11.593
Dec. 15, 2184 15,882,136 12.208

Images and Observations

255P/Levy's orbit is determined by observations dating back to Oct. 2, 2006. It was last officially observed on Oct. 7, 2021. The IAU Minor Planet Center records 503 observations used to determine its orbit.
