Key Facts

Overview

Comet 209P/LINEAR is an object whose orbit features a relatively short period, low inclination, and is controlled by Jupiter's gravitational effects. NASA JPL has classified 209P/LINEAR 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.

209P/LINEAR orbits the sun every 1,840 days (5.04 years), coming as close as 0.91 AU and reaching as far as 4.96 AU from the sun.

Close Approaches

209P/LINEAR's orbit is 0.05 AU from Earth's orbit at its closest point. This means that there is a wide berth between this asteroid and Earth at all times.

209P/LINEAR has 1 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
May 24, 2158 23,577,033 18.181
