Key Facts

Overview

Comet C/2013 C2 (Tenagra) is an object whose orbit is approximately between Jupiter and Neptune. NASA JPL has not classified Tenagra as potentially hazardous because its orbit does not bring it close to Earth.

Tenagra orbits the sun every 23,498 days (64.33 years), coming as close as 9.13 AU and reaching as far as 22.98 AU from the sun.

No Close Approaches

Tenagra's orbit is 8.17 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

Tenagra's orbit is determined by observations dating back to Feb. 14, 2013. It was last officially observed on June 29, 2019. The IAU Minor Planet Center records 477 observations used to determine its orbit.

Accessibility and Exploration

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