Overview

2023 EF3 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2023 EF3 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2023 EF3 orbits the sun every 1,490 days (4.08 years), coming as close as 0.77 AU and reaching as far as 4.33 AU from the sun. Based on its brightness and the way it reflects light, 2023 EF3 is probably between 0.167 to 0.373 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2023 EF3's orbit is 0.01 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 EF3 has 3 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
Aug. 18, 2027 24,092,132 31.803
Aug. 21, 2125 15,641,693 32.448
Aug. 25, 2178 6,940,787 33.736

Images and Observations

2023 EF3's orbit is determined by observations dating back to March 11, 2023. It was last officially observed on June 23, 2023. The IAU Minor Planet Center records 60 observations used to determine its orbit.
