Key Facts
- Categorized as a Main-belt Asteroid
- Comparable in size to the island of Manhattan (3.60 km diameter)
- Not a Near Earth Object
- Not a Potentially Hazardous Object
- See orbit simulation
Overview
Janpalous is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Janpalous as potentially hazardous because its orbit does not bring it close to Earth.
Janpalous orbits the sun every 1,280 days (3.50 years), coming as close as 2.13 AU and reaching as far as 2.47 AU from the sun. Janpalous is about 3.6 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.
The rotation of Janpalous has been observed. It completes a rotation on its axis every 5.15 hours.
No Close Approaches
Janpalous's orbit is 1.13 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
Janpalous's orbit is determined by observations dating back to March 20, 1996. It was last officially observed on Dec. 21, 2022. The IAU Minor Planet Center records 1,417 observations used to determine its orbit.
