Overview
2018 EE is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2018 EE as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2018 EE orbits the sun every 1,730 days (4.74 years), coming as close as 0.98 AU and reaching as far as 4.65 AU from the sun. Based on its brightness and the way it reflects light, 2018 EE is probably between 0.116 to 0.259 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a basketball court.
Close Approaches
2018 EE's orbit is 0.02 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.
2018 EE has 3 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| March 27, 2070 | 22,961,999 | 13.564 |
| Jan. 7, 2089 | 22,873,215 | 13.530 |
| Feb. 9, 2165 | 5,461,089 | 8.453 |
Images and Observations
2018 EE's orbit is determined by observations dating back to Oct. 27, 2017. It was last officially observed on June 4, 2018. The IAU Minor Planet Center records 249 observations used to determine its orbit.
