How far is far?

Light-years are easy to say and impossible to feel. Pick a world and see what the journey would actually cost — in time.

Travel time, one way

Times are one-way and assume constant speed — no acceleration, fuel, or course-correction, and they ignore the (small but real) relativistic effects near light speed. They're meant to convey scale, not to plan a trip. Distances are from the NASA Exoplanet Archive; light-year = 9.46 trillion km.
