55P/Tempel-Tuttle is a mid-sized comet with a medium-length orbit that is highly inclined to the ecliptic plane of the solar system. NASA JPL has classified 55P/Tempel-Tuttle 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.
55P/Tempel-Tuttle orbits the sun every 12,100 days (33.13 years), coming as close as 0.98 AU and reaching as far as 19.70 AU from the sun. Its orbit is highly elliptical. 55P/Tempel-Tuttle is about 3.6 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.
55P/Tempel-Tuttle'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.
55P/Tempel-Tuttle has 1 close approaches predicted in the coming decades:
|Date||Distance from Earth (km)||Velocity (km/s)|
|Dec. 18, 2163||19,819,587||70.225|
55P/Tempel-Tuttle's orbit is determined by observations dating back to Dec. 22, 1865. It was last officially observed on July 5, 1998. The IAU Minor Planet Center records 392 observations used to determine its orbit.
