Key Facts

Overview

2007 BD7 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2007 BD7 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2007 BD7 orbits the sun every 713 days (1.95 years), coming as close as 0.78 AU and reaching as far as 2.34 AU from the sun. Based on its brightness and the way it reflects light, 2007 BD7 is probably between 0.160 to 0.358 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

No Close Approaches

2007 BD7's orbit is 0.04 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.

Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.

Images and Observations

2007 BD7's orbit is determined by observations dating back to Jan. 23, 2007. It was last officially observed on Feb. 6, 2007. The IAU Minor Planet Center records 184 observations used to determine its orbit.

Accessibility and Exploration

This asteroid is not considered a viable target for human exploration by the NHATS study.
