Overview
2023 JE5 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2023 JE5 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.
2023 JE5 orbits the sun every 565 days (1.55 years), coming as close as 0.87 AU and reaching as far as 1.80 AU from the sun. Based on its brightness and the way it reflects light, 2023 JE5 is probably between 0.017 to 0.075 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
Close Approaches
2023 JE5's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is very close to Earth's orbit.
2023 JE5 has 7 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |

Images and Observations
2023 JE5's orbit is determined by observations dating back to May 13, 2023. It was last officially observed on June 1, 2023. The IAU Minor Planet Center records 42 observations used to determine its orbit.
Accessibility and Exploration
2023 JE5 can be reached with a journey of 370 days. This trajectory would require a delta-v of 10.608 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 3,990 potential trajectories and launch windows to this asteroid.
