Rigel is approximately 860 light-years away from Earth. Since a light-year is the distance light travels in one year, it would take light from Rigel 860 years to reach Earth. This means that the light we see from Rigel today actually left the star around the year 1160 AD.
Rigel is about 860 light years from us. That equates to 5.05550984 × 1015 miles. So at 100mph, it would take 50,555,100,000,000 hours or 5.7673032 × 109 years (That's almost 6 billion years)
The Earth will be long destroyed by our own sun before that happens.
It will take 8 minutes for the light from the sun to reach Earth. The actual heat of the sun does not reach all the way out to Earth. The warmth on Earth comes from the conversion of light energy to heat energy.
In our Solar System, we see light from our sun reflected off the planets. In more distant galaxies, light from many millions of stars takes a long time to reach the Earth. It takes light 4 years to reach the Earth from Sirius, a near neighbouring star. Using the Hubble telescope, we can see the light from the Eagle Nebula, which takes 7,000 years to reach the Earth.
When traveling at the speed of light, about 8 minutes. When walking, alot longer.

It takes approximately 8 minutes for the Sun's light to reach Earth.
It takes about 8 minutes and 20 seconds for light from the sun to reach the Earth.
About 37 years.
The light takes about 640 years to reach Earth, as Betelgeuse (a red supergiant star) is about 640 light years from Earth.
