Key Facts

Overview

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

Inouetakeshi orbits the sun every 1,560 days (4.27 years), coming as close as 2.13 AU and reaching as far as 3.12 AU from the sun. Based on its brightness and the way it reflects light, Inouetakeshi is probably between 2.874 to 6.427 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the island of Manhattan.

No Close Approaches

Inouetakeshi's orbit is 1.11 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

Inouetakeshi's orbit is determined by observations dating back to Feb. 22, 1991. It was last officially observed on Feb. 2, 2023. The IAU Minor Planet Center records 2,109 observations used to determine its orbit.

Accessibility and Exploration

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