The star Sirius A is 8.66 light-years from Earth. Imagine a spaceship that travels from Earth to Sirius A at a constant speed of 0.951c. On Earth, we would measure the time it takes for the ship to reach the star to be
(8.66 ly/0.951c)=9.11 years
(a)
How much time (in years) would it take the ship to travel from the Earth to the star as measured by an astronaut aboard the ship?
(b)
What is the distance to the star (in light years) as measured by an astronaut aboard the ship?

- The star Epsilon Eridani is 10.4 light-years from Earth. Imagine a spaceship that travels from Earth to Epsilon Eridani at a constant speed of 0.921c. On Earth, we would measure the time it takes for the ship to reach the star to be (10.4ly/0.921c)= 11.2 years. (a) How much time (in years) would it take the ship to travel from the Earth to the star as measured by a passenger aboard the ship? years (b) What is the distance to the star (in light years) as measured by a passenger aboard the ship?arrow_forwardChoose a unit distance in cm that would easily fit on a piece of paper. Let this be your scale distance, now divide your scale distance by 4.3 light years to get the scale that will allow you to convert between real distances and distances in your model. Scale = cm / 4.3 ly = cm / lyarrow_forwardA light-year is the distance that light can travel in one year.
