2P/Encke is a mid-sized comet whose orbit brings it closer to the sun than Jupiter. NASA JPL has classified 2P/Encke 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.
2P/Encke orbits the sun every 1,200 days (3.29 years), coming as close as 0.34 AU and reaching as far as 4.09 AU from the sun. Its orbit is highly elliptical. 2P/Encke is about 4.8 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.
The rotation of 2P/Encke has been observed. It completes a rotation on its axis every 11.08 days.
2P/Encke's orbit is 0.17 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.
2P/Encke has 4 close approaches predicted in the coming decades:
|Date||Distance from Earth (km)||Velocity (km/s)|
|July 7, 2063||29,041,546||32.454|
|June 28, 2106||29,392,803||25.675|
|June 29, 2172||24,916,304||26.582|
|Nov. 6, 2178||28,472,781||32.264|
2P/Encke's orbit is determined by observations dating back to Aug. 15, 2009. It was last officially observed on Dec. 28, 2019. The IAU Minor Planet Center records 2,584 observations used to determine its orbit.
