Key Facts

Overview

Narcissus is a relatively small asteroid with an orbit between Jupiter and Neptune. NASA JPL has not classified Narcissus as potentially hazardous because its orbit does not bring it close to Earth.

Narcissus orbits the sun every 6,593 days (18.05 years), coming as close as 3.07 AU and reaching as far as 10.69 AU from the sun. Narcissus is about 11.2 kilometers in diameter, making it larger than most asteroids, comparable in size to the city of Cleveland, Ohio.

No Close Approaches

Narcissus's orbit is 2.09 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.

Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.

Images and Observations

Narcissus's orbit is determined by observations dating back to March 7, 1984. It was last officially observed on Oct. 22, 2018. The IAU Minor Planet Center records 288 observations used to determine its orbit.

Accessibility and Exploration

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