249047 (2007 TC91)

Key Facts

• Categorized as a Outer Main-belt Asteroid
• Comparable in size to the San Francisco Bay
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

249047 (2007 TC91) 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 2007 TC91 as potentially hazardous because its orbit does not bring it close to Earth.

2007 TC91 orbits the sun every 3,320 days (9.09 years), coming as close as 3.96 AU and reaching as far as 4.75 AU from the sun. Based on its brightness and the way it reflects light, 2007 TC91 is probably between 4.042 to 9.037 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.

No Close Approaches

2007 TC91's orbit is 2.95 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

2007 TC91's orbit is determined by observations dating back to June 7, 1994. It was last officially observed on June 23, 2023. The IAU Minor Planet Center records 338 observations used to determine its orbit.

Accessibility and Exploration

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