Overview
2020 BE1 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2020 BE1 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2020 BE1 orbits the sun every 821 days (2.25 years), coming as close as 0.85 AU and reaching as far as 2.58 AU from the sun. Based on its brightness and the way it reflects light, 2020 BE1 is probably between 0.130 to 0.290 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a basketball court.
Close Approaches
2020 BE1's orbit is 0.05 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.
2020 BE1 has 7 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| July 12, 2103 | 28,367,484 | 23.630 |
| July 8, 2112 | 18,493,429 | 22.206 |
| July 6, 2121 | 11,367,246 | 21.128 |
| July 4, 2130 | 7,918,192 | 20.533 |
| July 5, 2139 | 8,247,687 | 20.570 |
| July 5, 2148 | 11,740,197 | 21.198 |
| July 9, 2157 | 20,994,688 | 22.554 |
