Key Facts

Overview

15883 (1997 CR29) is a average-sized asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 1997 CR29 as potentially hazardous because its orbit does not bring it close to Earth.

1997 CR29 orbits the sun every 117,606 days (321.99 years), coming as close as 37.11 AU and reaching as far as 56.85 AU from the sun. Based on its brightness and the way it reflects light, 1997 CR29 is probably between 101.054 to 225.964 kilometers in diameter, making it larger than most asteroids, very roughly comparable in size to the U.S. state of Connecticut.

No Close Approaches

1997 CR29's orbit is 36.16 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 CR29's orbit is determined by observations dating back to Feb. 3, 1997. It was last officially observed on March 14, 2013. The IAU Minor Planet Center records 32 observations used to determine its orbit.

Accessibility and Exploration

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