DDS Distances #3 Speed of light = 300,000 km/s distance of a single light year = 9,460,000,000,000 km Explain with words and support with numbers a. The star Sirius is 8.56 light years away from Earth. How would you determine how far that is in kilometers? How long does it take the light from Sirius to reach Earth? b. The star Castor is 488,000,000,000,000 kilometers away from Earth. How would you determine how far that is in light years? How long does it take the light from Castor to reach Earth?
