Key Facts

Overview

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

Nobuyuki orbits the sun every 1,760 days (4.82 years), coming as close as 2.16 AU and reaching as far as 3.55 AU from the sun. Nobuyuki is about 6.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.

No Close Approaches

Nobuyuki's orbit is 1.17 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

Nobuyuki's orbit is determined by observations dating back to Feb. 7, 1989. It was last officially observed on June 21, 2023. The IAU Minor Planet Center records 2,225 observations used to determine its orbit.

Accessibility and Exploration

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