# How long would it take to travel 1 light year

Asked by wiki @ in Physics viewed by 376 People

Light travels at a constant speed of about 300,000 km/s. This speed is referred to as the speed of light. A light year is the distance that light travels in one year. One light year is equal to 9.46 trillion kilometers. The closest star to Earth, other than the Sun, is Proxima Centauri. It takes light from this star about 4.2 years to reach Earth. How far from Earth is the star Proxima Centauri? A. 4.2 light years B. 9.46 trillion km C. 300,000 light years D. 300,000 km.

Based on the information in the question, a light year is the distance traveled light in one year. Then if the light from the star Centauri takes 4.2 years to reach the earth, then its distance from earth is 4.2 light years.
