7P/Pons-Winnecke is a mid-sized comet whose orbit features a relatively short period, low inclination, and is controlled by Jupiter's gravitational effects. NASA JPL has classified 7P/Pons-Winnecke 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.
7P/Pons-Winnecke orbits the sun every 2,330 days (6.38 years), coming as close as 1.26 AU and reaching as far as 5.62 AU from the sun. 7P/Pons-Winnecke is about 5.2 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.
7P/Pons-Winnecke's orbit is 0.24 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.
7P/Pons-Winnecke has 3 close approaches predicted in the coming decades:
|Date||Distance from Earth (km)||Velocity (km/s)|
|June 12, 2062||25,078,521||16.270|
|Aug. 1, 2073||29,077,860||17.329|
|June 15, 2142||26,173,371||12.892|
7P/Pons-Winnecke's orbit is determined by observations dating back to April 28, 1921. It was last officially observed on Feb. 2, 2020. The IAU Minor Planet Center records 674 observations used to determine its orbit.
