The nearest star to Earth besides the Sun is Proxima Centauri, which is a distance of approximately 4 light years away. A planet that may be able to sustain liquid water on its surface was discovered in 2016 orbiting Proxima Centauri. According to observers on Earth, a spaceship that travels at 0.9c should be able to reach the planet in 3.6 years. How long would the trip take according to astronauts on board the spaceship?
