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?

Proxima Centauri, the nearest start to the Sun, is about 4 light years from Earth, and Antares is about 520 light years from Earth. Antares is a very bright star easily seen with the naked eye but Proxima Centauri is so dim that a small telescope is needed to see it. What can you say about the relative luminosities of Antares and Proxima Centauri?

ANSWER 3A, B, AND C! 3. The star system that is closest to the earth is Alpha Centauri. It is 4.37 light years away in Earth's reference frame. The fastest spacecraft humans have ever launched is New Horizons, which sent us sweet pictures of Pluto in 2015. It attained a speed of 45 km/s relative to the sun. That's fast, but even at this rate, interstellar travel is not practical. a) Traveling at 45 km/s, how long, in years, would...
