The Interstellar Travel Planner
Have you ever woken up aboard an interstellar spacecraft with no idea how long it will take to get home to Earth? Then you need the Interstellar Map . This impressive browser-based visualization combines a 3D map of nearby stars with a relativistic travel-time calculator , allowing you to explore the practical consequences of planned journeys across interstellar space. The map plots thousands of named stars in three-dimensional space relative to the Sun and lets you calculate how long it would take to travel between any two stars - in both ship time and Earth time . The interface includes search tools for finding stars by name or constellation. Or simply click on the map to choose where you’re leaving from - and where in the galaxy you’re headed. When you select a destination, the tool calculates your journey based on constant proper acceleration and special relativity . If you've seen Project Hail Mary you may already be familiar with the idea of a constantly accelerating star...
