Starship Enterprise vs. Superman: Who's the Fastest Sci-Fi Spacefarer? (Graphic)

If the fictional USS Enterprise raced the ship from "Battlestar Galactica" to the nearest star system, which would get there first? When leaving Earth on a voyage to Alpha Centauri, it turns out, Galactica would get there in just 29 minutes, traveling at an average speed of 53.4 trillion miles per hour (85.9 trillion kilometers per hour). The USS Enterprise from "Star Trek" would take more than 161 days, at a speed of "just" 6.6 billion mph (10.6 km/h).
