Yamada

Key Facts

• Categorized as a Main-belt Asteroid
• Comparable in size to the city of Cleveland, Ohio (12.52 km diameter)
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

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

Yamada orbits the sun every 1,490 days (4.08 years), coming as close as 2.35 AU and reaching as far as 2.76 AU from the sun. Yamada is about 12.5 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Cleveland, Ohio.

The rotation of Yamada has been observed. It completes a rotation on its axis every 4.03 hours.

No Close Approaches

Yamada's orbit is 1.33 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

Yamada's orbit is determined by observations dating back to Jan. 13, 1931. It was last officially observed on July 4, 2023. The IAU Minor Planet Center records 4,795 observations used to determine its orbit.
