Janetsong

Key Facts

• Categorized as a Main-belt Asteroid
• Comparable in size to the island of Manhattan (4.22 km diameter)
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

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

Janetsong orbits the sun every 1,470 days (4.02 years), coming as close as 2.29 AU and reaching as far as 2.76 AU from the sun. Janetsong is about 4.2 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.

The rotation of Janetsong has been observed. It completes a rotation on its axis every 4.36 hours.

No Close Approaches

Janetsong's orbit is 1.29 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

Janetsong's orbit is determined by observations dating back to Jan. 16, 1993. It was last officially observed on July 2, 2023. The IAU Minor Planet Center records 2,208 observations used to determine its orbit.

Accessibility and Exploration

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