Gaidai

Key Facts

• Categorized as a Main-belt Asteroid
• Comparable in size to the San Francisco Bay
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

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

Gaidai orbits the sun every 1,690 days (4.63 years), coming as close as 2.31 AU and reaching as far as 3.23 AU from the sun. Based on its brightness and the way it reflects light, Gaidai is probably between 4.232 to 9.463 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.

No Close Approaches

Gaidai's orbit is 1.31 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

Gaidai's orbit is determined by observations dating back to Sept. 11, 1977. It was last officially observed on June 28, 2023. The IAU Minor Planet Center records 2,674 observations used to determine its orbit.

Accessibility and Exploration

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