2019 BZ3 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2019 BZ3 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.
2019 BZ3 orbits the sun every 1,270 days (3.48 years), coming as close as 0.97 AU and reaching as far as 3.62 AU from the sun. Based on its brightness and the way it reflects light, 2019 BZ3 is probably between 0.005 to 0.010 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2019 BZ3's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
2019 BZ3 has 1 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Jan. 27, 2019 | 48,128 | 11.372 |
2019 BZ3's orbit is determined by observations dating back to Jan. 28, 2019. It was last officially observed on Feb. 5, 2019. The IAU Minor Planet Center records 30 observations used to determine its orbit.
