The average distance between two neighboring stars in our galaxy is about 5 light-years.
(a) How many years would it take the Voyager 1 Space Probe to travel 5 light-years?
(b) If an alien civilization built a spaceship that can travel 5 light-years in 1000 years. How many kilometers does this spaceship travel in 1 second? (hint: Google “how far is 1 light-year”)

Earth's neighboring galaxy, the Andromeda Galaxy, is a distance of 2.54×107 light-years from Earth. If the lifetime of a human is taken to be 75.0 years, a spaceship would need to achieve some minimum speed ?min to deliver a living human being to this galaxy. How close to the speed of light would this minimum speed be? Express your answer as the difference between ?min and the speed of light ?. ?−?min= __________ m/s

On average over time, about 4 new stars form every year in our Galaxy. That is, about 4 protostars reach the zero-age main sequence and start burning hydrogen. Assuming that it takes 1.5 million years for a recognizable protostar to reach the ZAMS, once it is formed, how many protostars are there at any one time in our Galaxy?

f) in vacuum, light travels at about 186,282 miles per second. One mile is about 161 kilometers (km). Astronomers prefer to use units of distance that are reasonable in describing how far objects are from Earth. For example, for distances in the solar system we use the astronomical unit (AU), which is equal to the average distance of Earth from the Sun; 1 AU is about 150 million km. For distances to stars and galaxies, astronomers use the light-year (1...

Two stars z and p, are exactly in the opposite directions from the Earth. The distance to 'z' from earth is 80 light-years. The distance to 'p' is 90 light-years. Zerah takes off in the direction of z, at a speed of 0.8 c, while Perez takes off in the direction of p at the speed 0.9c. (distance between two stars in earth frame = 170c*y) (time to each star in earth frame = 100 years, simultaneous events in earth's...
