- The 5 hours it takes light to travel across our Solar System may seem like a short period to cross such a large distance, but we have to think about scale.

It takes light about 40 times longer (Pluto at a distance of 39.4 A.U.) to leave the Solar System or about 5 hours. The speed of light is a built-in quality of our universe. All evidence to date indicates that light has always traveled at this speed, that the speed is exact, and that the same speed is observed for all observers. The vast size ...

May 18, 2020 · For much greater distances — interstellar distances — astronomers use light years. A light year is the distance a photon of light travels in one year, which is about 6 trillion miles (9 trillion kilometers, or 63,000 AU).
Below are the distances between the Sun and the planets belonging to the Solar System in light time. Mercury : 3,3 light minutes; Venus : 6 light minutes; Earth : 8,3 light minutes; Mars : 12,7 light minutes; Jupiter : 43 light minutes; Saturn : 1,3 light hours; Uranus : 2,7 light hours; Neptune : 4,2 light hours
Apr 7, 2018 · There is no correct point where solar system ends. Voyager 1 which is in the outer limits of solar system is at present 141.astronomical units. So it will take 192.7 hours. as light takes 8,2 minutes for 1 AU,
Jun 11, 2018 · In fact, it's common to measure planet distances from the sun in light minutes or light hours as opposed to light years, since those numbers are smaller and easier to comprehend. For instance, Mercury is the closest planet to the sun. On average, it is about 36 million miles away.
Apr 28, 2024 · Sunlight takes an average of 8 minutes and 20 seconds to reach Earth. The duration for sunlight to reach Earth varies based on the Earth’s elliptical orbit around the Sun. Photons emitted from the Sun’s surface undergo interactions and absorption within the Sun before reaching Earth.

Light is the fastest thing in our Universe traveling through interstellar space at 186,000 miles/second (300,000 km/sec). In one year, light can travel 5.88 trillion miles (9.46 trillion km). A light year is a basic unit astronomers use to measure the vast distances in space.
