Overview

2023 BA10 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2023 BA10 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2023 BA10 orbits the sun every 1,480 days (4.05 years), coming as close as 0.49 AU and reaching as far as 4.59 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2023 BA10 is probably between 0.312 to 0.698 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to the U.S. Capitol building.

Close Approaches

2023 BA10's orbit is 0.03 AU from Earth's orbit at its closest point. This means that there is a wide berth between this asteroid and Earth at all times.

2023 BA10 has 2 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
March 9, 2023 9,683,533 28.193
Sept. 22, 2043 20,346,306 24.273

Images and Observations

2023 BA10's orbit is determined by observations dating back to Jan. 19, 2023. It was last officially observed on March 4, 2023. The IAU Minor Planet Center records 169 observations used to determine its orbit.

Accessibility and Exploration

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