Key Facts

Overview

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

Ikeda orbits the sun every 2,030 days (5.56 years), coming as close as 2.68 AU and reaching as far as 3.59 AU from the sun. Ikeda is about 9.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.

The rotation of Ikeda has been observed. It completes a rotation on its axis every 16.33 hours.

No Close Approaches

Ikeda's orbit is 1.70 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

Ikeda's orbit is determined by observations dating back to Dec. 12, 1991. It was last officially observed on Nov. 26, 2022. The IAU Minor Planet Center records 4,574 observations used to determine its orbit.

Accessibility and Exploration

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