Overview

Cuyo is a small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified Cuyo 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.

Cuyo orbits the sun every 1,151 days (3.15 years), coming as close as 1.06 AU and reaching as far as 3.24 AU from the sun. Cuyo is about 5.7 kilometers in diameter, making it larger than most asteroids, comparable in size to the San Francisco Bay.

The rotation of Cuyo has been observed. It completes a rotation on its axis every 2.69 days.

Cuyo's spectral type (Tholen) / Sl (SMASSII) indicates that it is likely to contain magnesium silicate and iron silicate.

Close Approaches

Cuyo's orbit is 0.07 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.

Cuyo has 4 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
Oct. 6, 2030 13,413,851 14.447
Oct. 7, 2071 15,616,500 14.417
Sept. 24, 2131 28,311,507 16.405
Oct. 2, 2172 10,912,320 14.753

Images and Observations

Cuyo's orbit is determined by observations dating back to May 6, 1954. It was last officially observed on June 3, 2019. The IAU Minor Planet Center records 2,041 observations used to determine its orbit.

Accessibility and Exploration

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