On August 27, 2003, Mars approached as close to Earth as it will for over 50,000 years. If its angular size (the planet's diameter, measured by the angle the radius subtends) on that day was measured by an astronomer to be 24.9 seconds of arc, and its diameter is known to be 6784 km, how close was the approach distance? Be sure to use an appropriate number of significant figures in your answer.
