Key Facts

Overview

Asteroid 1997 TN is an object with an orbit between Jupiter and Neptune. NASA JPL has not classified 1997 TN as potentially hazardous because its orbit does not bring it close to Earth.

1997 TN orbits the sun every 5,900 days (16.15 years), coming as close as 2.25 AU and reaching as far as 10.53 AU from the sun.

No Close Approaches

1997 TN's orbit is 1.26 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 TN's orbit is determined by observations dating back to Oct. 2, 1997. It was last officially observed on Oct. 4, 1997. The IAU Minor Planet Center records 18 observations used to determine its orbit.

Accessibility and Exploration

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