Comet 289P/Blanpain is an object whose orbit features a relatively short period, low inclination, and is controlled by Jupiter's gravitational effects. NASA JPL has classified 289P/Blanpain 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.
289P/Blanpain orbits the sun every 1,940 days (5.31 years), coming as close as 0.96 AU and reaching as far as 5.13 AU from the sun.
289P/Blanpain's orbit is 0.02 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.
289P/Blanpain has 4 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Jan. 11, 2020 | 13,588,735 | 12.194 |
| Nov. 6, 2035 | 12,304,258 | 12.612 |
