11. How will you get there? The fastest spacecraft made so far (the Helios spacecraft) traveled at 250,000 km/h (150,000 mph). At this speed, the Sun is about 600 hours (25 days) away. Kepler-62 is 37.5 billion hours (4.3 million years) away. Trappist-1 is 1.5 billion hours (170,000 years) away. Obviously, we need a faster spacecraft. Suppose that we invent a way to travel at 0.999 times the speed of light. Ar that speed (0.999 light-years per year), how long will it take (according to an observer on Earth) for you to travel to the stellar planetary system Kepler-62? (Hint: Kepler-62 is 990 light-years from Earth. You would divide that distance by 1 light-year per year if we could travel at light speed.) 12. How long would it take to travel to Trappist-1, traveling at 0.999 light-years per year
