Overview
2019 BC1 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2019 BC1 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2019 BC1 orbits the sun every 1,470 days (4.02 years), coming as close as 0.93 AU and reaching as far as 4.14 AU from the sun. Based on its brightness and the way it reflects light, 2019 BC1 is probably between 0.237 to 0.530 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to a football field.
Close Approaches
2019 BC1's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
2019 BC1 has 2 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Jan. 10, 2023 | 10,990,440 | 13.781 |
| Jan. 27, 2027 | 13,706,959 | 16.642 |
Images and Observations
2019 BC1's orbit is determined by observations dating back to Sept. 16, 2010. It was last officially observed on April 10, 2023. The IAU Minor Planet Center records 161 observations used to determine its orbit.
