Actually, it's WORSE. 1 light year = 9.454 x 10^15 meters 22 light years = 2.080 x 10^17 meters SF to Paris, round trip = 1.877 x 10^7 meters Number of trips = 1.108 x 10^10 In layman's terms, it's about 11 billion trips! Here's another way to get a sense of scale. The earth rotates the sun at an orbit with semi-major axis of about 150 million kilometers. Using some data you can determine that the orbit of Earth is about 9.398 x 10^11 meters in circumference. Divide the distance to the star by this number to get 2.213 x 10^5 years. That is, it takes the Earth about 220 thousand years to go this distance around the sun.
