Key Facts
- Categorized as a Outer Main-belt Asteroid
- Comparable in size to the U.S. Pentagon
- Not a Near Earth Object
- Not a Potentially Hazardous Object
- See orbit simulation
Overview
2019 AN15 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 2019 AN15 as potentially hazardous because its orbit does not bring it close to Earth.
2019 AN15 orbits the sun every 2,090 days (5.72 years), coming as close as 3.02 AU and reaching as far as 3.38 AU from the sun. Based on its brightness and the way it reflects light, 2019 AN15 is probably between 1.144 to 2.559 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. Pentagon.
No Close Approaches
2019 AN15's orbit is 2.04 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
2019 AN15's orbit is determined by observations dating back to April 8, 2014. It was last officially observed on Oct. 17, 2022. The IAU Minor Planet Center records 68 observations used to determine its orbit.
