Question

The Voyager I spacecraft was launched in 1977 and is now travelling away from our solar system in interstellar space. It is currently a distance of 152 AU from Earth. (AU stands for astronomical units; 1 AU is the distance from the Sun to the Earth, 1.50 × 10¹¹ m. 1 light year is the distance light travels in one year.) a) How many hours does it take for a radio signal sending data from Voyager I to reach Earth? [1 points] b) At its current speed, 6.08 × 10? km/h, how long would it take for Voyager I to reach the nearest known exoplanet, which orbits Proxima Centauri (4.24 light years away)? (Express your answer in years.) [3 points]
