Key Facts

Overview

Guayaquil is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Guayaquil as potentially hazardous because its orbit does not bring it close to Earth.

Guayaquil orbits the sun every 1,420 days (3.89 years), coming as close as 2.23 AU and reaching as far as 2.72 AU from the sun. Guayaquil is about 10.2 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Boston.

No Close Approaches

Guayaquil's orbit is 1.22 AU from Earth's orbit at its closest point. This means that there is an extremely 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

Guayaquil's orbit is determined by observations dating back to April 4, 1989. It was last officially observed on Feb. 19, 2023. The IAU Minor Planet Center records 2,425 observations used to determine its orbit.

Accessibility and Exploration

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