It takes a ray of light, not years, but just a few hours (about 7 hours) to reach Pluto.
It takes 5 hours 28 minutes and 30 seconds for light from the sun to reach Pluto.
Pluto's distance from the Sun is from 4.4 to 7.4 billion kilometers. The speed of light is 300,000 km/sec. Light takes between from 4.1 hours and 6.8 hours to travel from the Sun to Pluto. For the mean distance of 5.9 billion km, it would take 5.46 hours.
Pluto's orbit is highly eccentric. When Pluto is at its minimum distance form the Sun, sunlight takes about 14800 seconds to reach it (just over 4 hours). At its maximum, the light takes about 24600 seconds (nearly 7 hours).
The closest Pluto gets to the Sun is 4.4 billion kilometers, which means that light from the Sun always takes longer than 4 hours to reach Pluto. For a rocket vehicle travelling at the speed that astronauts went to our Moon (less than 40,000 km/hr), it would take over 12 years to reach Pluto!
Because it only takes 8 minutes for sunlight to reach Earth, but it takes 4 hours to reach Neptune.
roughly 14years at 13km/s.
Light years.
If you mean light from the Sun, then it takes eight minutes for the light to reach the Earth.
it does reach the earth in light energy.
800,0000
the light speed are very fast so light easily reach on earth
