187799 (1999 FK16)

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

187799 (1999 FK16) 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 FK16 as potentially hazardous because its orbit does not bring it close to Earth.

1999 FK16 orbits the sun every 3,240 days (8.87 years), coming as close as 3.07 AU and reaching as far as 5.50 AU from the sun. Based on its brightness and the way it reflects light, 1999 FK16 is probably between 3.440 to 7.692 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the island of Manhattan.

No Close Approaches

1999 FK16's orbit is 2.06 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 FK16's orbit is determined by observations dating back to March 21, 1999. It was last officially observed on Jan. 23, 2023. The IAU Minor Planet Center records 325 observations used to determine its orbit.

Accessibility and Exploration

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