Overview
2019 CE4 is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2019 CE4 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2019 CE4 orbits the sun every 1,760 days (4.82 years), coming as close as 0.97 AU and reaching as far as 4.74 AU from the sun. Based on its brightness and the way it reflects light, 2019 CE4 is probably between 0.641 to 1.432 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.
Close Approaches
2019 CE4'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.
2019 CE4 has 5 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Oct. 16, 2023 | 19,208,742 | 15.185 |
| Oct. 14, 2085 | 21,526,011 | 16.396 |
| Oct. 28, 2099 | 16,131,305 | 17.096 |
| Oct. 30, 2113 | 16,727,318 | 17.301 |
| Oct. 14, 2155 | 22,506,545 | 16.619 |
