Key Facts

Overview

Agastrophus is a mid-sized asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified Agastrophus as potentially hazardous because its orbit does not bring it close to Earth.

Agastrophus orbits the sun every 4,220 days (11.55 years), coming as close as 4.77 AU and reaching as far as 5.45 AU from the sun. Based on its brightness and the way it reflects light, Agastrophus is probably between 7.024 to 15.705 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.

No Close Approaches

Agastrophus's orbit is 3.78 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

Agastrophus's orbit is determined by observations dating back to Oct. 6, 1997. It was last officially observed on Feb. 19, 2023. The IAU Minor Planet Center records 598 observations used to determine its orbit.

Accessibility and Exploration

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