Overview

2017 BD29 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2017 BD29 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2017 BD29 orbits the sun every 331 days (0.91 years), coming as close as 0.65 AU and reaching as far as 1.22 AU from the sun. Based on its brightness and the way it reflects light, 2017 BD29 is probably between 0.080 to 0.356 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2017 BD29'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.

2017 BD29 has 23 close approaches predicted in the coming decades:

Images and Observations

2017 BD29's orbit is determined by observations dating back to Jan. 26, 2017. It was last officially observed on May 27, 2018. The IAU Minor Planet Center records 181 observations used to determine its orbit.

Accessibility and Exploration

2017 BD29 can be reached with a journey of 394 days. This trajectory would require a delta-v of 11.394 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 238 potential trajectories and launch windows to this asteroid.
