K- A light-year is the distance light travels in empty space in one year. (a) Light travels at a speed of 186,000 miles per second. The star nearest the sun is Proxima Centauri, in the constellation Centaurus, whose distance from Earth is 4 light years. What is the distance to Proxima Centauri in miles? (b) In metric measurements, the speed of light is 3.00 x 10 meters per second. Verify that a light-year is about 1016 meters. (a) The distance to Proxima Centauri is about trillion miles. (Type an integer or a decimal rounded to one decimal place as needed.) K- A light-year is the distance light travels in empty space in one year.
