Key Facts
- Categorized as a Main-belt Asteroid
- Comparable in size to the island of Manhattan (3.76 km diameter)
- Not a Near Earth Object
- Not a Potentially Hazardous Object
- See orbit simulation
Overview
Kinwalaniihsia is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Kinwalaniihsia as potentially hazardous because its orbit does not bring it close to Earth.
Kinwalaniihsia orbits the sun every 1,350 days (3.70 years), coming as close as 2.19 AU and reaching as far as 2.58 AU from the sun. Kinwalaniihsia is about 3.8 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.
No Close Approaches
Kinwalaniihsia's orbit is 1.18 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
Kinwalaniihsia's orbit is determined by observations dating back to Oct. 25, 1981. It was last officially observed on April 8, 2023. The IAU Minor Planet Center records 3,358 observations used to determine its orbit.
Accessibility and Exploration
This asteroid is not considered a viable target for human exploration by the NHATS study.Similar Objects
