Overview

Syrinx is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified Syrinx 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.

Syrinx orbits the sun every 1,414 days (3.87 years), coming as close as 0.63 AU and reaching as far as 4.30 AU from the sun. Its orbit is highly elliptical. Syrinx is about 1.8 kilometers in diameter, making it larger than most asteroids, comparable in size to Mount Everest.

Close Approaches

Syrinx's orbit is 0.11 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.

Syrinx has 3 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
Nov. 2, 2085 24,409,798 26.054
Oct. 25, 2108 28,996,277 21.253
Nov. 1, 2193 14,397,896 25.345

Images and Observations

Syrinx's orbit is determined by observations dating back to Nov. 4, 1981. It was last officially observed on March 27, 2019. The IAU Minor Planet Center records 467 observations used to determine its orbit.

Accessibility and Exploration

This asteroid is not considered a viable target for human exploration by the NHATS study.
