Key Facts

Overview

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

Truong orbits the sun every 1,510 days (4.13 years), coming as close as 2.45 AU and reaching as far as 2.71 AU from the sun. Truong is about 2.9 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to Mount Everest.

No Close Approaches

Truong's orbit is 1.46 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

Truong's orbit is determined by observations dating back to March 12, 1986. It was last officially observed on May 8, 2023. The IAU Minor Planet Center records 2,228 observations used to determine its orbit.

Accessibility and Exploration

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