2017 BX is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2017 BX 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.
2017 BX orbits the sun every 644 days (1.76 years), coming as close as 0.94 AU and reaching as far as 1.98 AU from the sun. Based on its brightness and the way it reflects light, 2017 BX is probably between 0.004 to 0.020 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2017 BX's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is very close to Earth's orbit.
2017 BX has 1 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| April 25, 2024 | 21,735,017 | 10.543 |
2017 BX's orbit is determined by observations dating back to Jan. 20, 2017. It was last officially observed on Jan. 25, 2017. The IAU Minor Planet Center records 75 observations used to determine its orbit.
2017 BX can be reached with a journey of 330 days. This trajectory would require a delta-v of 11.907 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 12 potential trajectories and launch windows to this asteroid.
