Key Facts

Overview

Hoshi-no-ie is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Hoshi-no-ie as potentially hazardous because its orbit does not bring it close to Earth.

Hoshi-no-ie orbits the sun every 1,920 days (5.26 years), coming as close as 2.67 AU and reaching as far as 3.37 AU from the sun. Hoshi-no-ie is about 21.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Indianapolis.

No Close Approaches

Hoshi-no-ie'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

Hoshi-no-ie's orbit is determined by observations dating back to Nov. 24, 1948. It was last officially observed on May 15, 2023. The IAU Minor Planet Center records 3,722 observations used to determine its orbit.

Accessibility and Exploration

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