162232 (1999 TC154)

Key Facts

• Categorized as a Outer 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

162232 (1999 TC154) is a mid-sized asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified 1999 TC154 as potentially hazardous because its orbit does not bring it close to Earth.

1999 TC154 orbits the sun every 2,920 days (7.99 years), coming as close as 2.56 AU and reaching as far as 5.43 AU from the sun. Based on its brightness and the way it reflects light, 1999 TC154 is probably between 2.901 to 6.487 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the island of Manhattan.

No Close Approaches

1999 TC154's orbit is 1.57 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

1999 TC154's orbit is determined by observations dating back to Oct. 4, 1999. It was last officially observed on June 30, 2023. The IAU Minor Planet Center records 613 observations used to determine its orbit.
