19909 (4326 T-3)

Key Facts

• Categorized as a Main-belt Asteroid
• Comparable in size to the island of Manhattan
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

19909 (4326 T-3) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 4326 T-3 as potentially hazardous because its orbit does not bring it close to Earth.

4326 T-3 orbits the sun every 1,370 days (3.75 years), coming as close as 2.04 AU and reaching as far as 2.79 AU from the sun. Based on its brightness and the way it reflects light, 4326 T-3 is probably between 2.492 to 5.572 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the island of Manhattan.

The rotation of 4326 T-3 has been observed. It completes a rotation on its axis every 39.79 hours.

No Close Approaches

4326 T-3's orbit is 1.04 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

4326 T-3's orbit is determined by observations dating back to Oct. 7, 1977. It was last officially observed on March 5, 2023. The IAU Minor Planet Center records 3,854 observations used to determine its orbit.

Accessibility and Exploration

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