Overview
138205 (2000 EZ148) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2000 EZ148 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.
2000 EZ148 orbits the sun every 1,520 days (4.16 years), coming as close as 1.00 AU and reaching as far as 4.17 AU from the sun. Based on its brightness and the way it reflects light, 2000 EZ148 is probably between 2.492 to 5.572 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the island of Manhattan.
Close Approaches
2000 EZ148's orbit is 0.09 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.
2000 EZ148 has 4 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| July 10, 2025 | 29,887,321 | 10.137 |
| Aug. 21, 2050 | 19,886,923 | 9.441 |
| July 26, 2075 | 27,075,519 | 9.714 |
| Sept. 14, 2187 | 18,074,574 | 14.015 |
