Overview
481327 (2006 BB27) is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2006 BB27 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2006 BB27 orbits the sun every 581 days (1.59 years), coming as close as 1.03 AU and reaching as far as 1.70 AU from the sun. 2006 BB27 is about 0.2 kilometers in diameter, making it a small to average asteroid, comparable in size to a football field.
Close Approaches
2006 BB27'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.
2006 BB27 has 5 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Aug. 1, 2049 | 9,386,045 | 14.764 |
| Aug. 5, 2076 | 10,865,239 | 15.461 |
| Aug. 1, 2111 | 15,558,343 | 14.543 |
