  • Not a Near Earth Object
  • Not a Potentially Hazardous Object
  • See orbit simulation

Overview

13694 (1997 WW7) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 1997 WW7 as potentially hazardous because its orbit does not bring it close to Earth.

1997 WW7 orbits the sun every 4,420 days (12.10 years), coming as close as 4.90 AU and reaching as far as 5.65 AU from the sun. 1997 WW7 is about 29.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Indianapolis.

The rotation of 1997 WW7 has been observed. It completes a rotation on its axis every 30.64 hours.

No Close Approaches

1997 WW7's orbit is 3.91 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

1997 WW7's orbit is determined by observations dating back to Feb. 11, 1989. It was last officially observed on May 7, 2023. The IAU Minor Planet Center records 2,666 observations used to determine its orbit.

Accessibility and Exploration

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