Key Facts

Overview

16329 (3255 T-2) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 3255 T-2 as potentially hazardous because its orbit does not bring it close to Earth.

3255 T-2 orbits the sun every 1,730 days (4.74 years), coming as close as 2.61 AU and reaching as far as 3.03 AU from the sun. Based on its brightness and the way it reflects light, 3255 T-2 is probably between 2.201 to 4.921 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.

No Close Approaches

3255 T-2's orbit is 1.59 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

3255 T-2's orbit is determined by observations dating back to Sept. 19, 1973. It was last officially observed on May 20, 2023. The IAU Minor Planet Center records 1,081 observations used to determine its orbit.

Accessibility and Exploration

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