Ten parsecs is about ________.

Question

Quizplus · Accepted Answer

A parsec is a unit of distance equivalent to 3.26 light-years. Therefore, ten parsecs would be equivalent to 10 x 3.26 = 32.6 light-years. Choice A is incorrect because 150 million kilometers is only about 0.0016 light-years, which is much smaller than ten parsecs. Choice C is incorrect because 10,000 seconds is only about 2.8 hours, which is a measure of time rather than distance. Choice D is incorrect because the parallax second of angle is a unit of measurement for stellar distances based on the parallax effect, not a direct measure of distance.
