Sunlight takes approximately 13 minutes to travel from the Sun to Mars. This duration is based on the speed of light, which travels at approximately 299,792 kilometers per second in a vacuum.
From an average distance of 142 million miles, Mars is 1.5 astronomical units (AU) away from the Sun. The 13-minute travel time of sunlight is important for understanding the timing of solar phenomena on Mars, including sunrise and sunset throughout the Martian day.
