The star Rigel, which has a visual magnitude of 0.18, is listed as the beta star in Orion (Beta Orionis). It has approximately 17 solar masses (17M), and is something on the order of 62 times the sun's radius. If Rigel was where our sun is, its outer boundaries would extend out around where the asteroid belt is. It would completely engulf all the inner planets.

Its distance is not known very precisely, but it must be something around 800 light-years. That would mean it takes the light 800 years to reach Earth.
750 ~ 900 light years 773 light years from earth, per wikipedia.
Wikipedia lists its distance as 860 ± 80 light-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.
Rigel and Betelgeuse don't orbit each other. They are hundreds of light-years away from each other.
It takes approximately 8 minutes for the Sun's light to reach Earth.
The light takes about 640 years to reach Earth, as Betelgeuse (a red supergiant star) is about 640 light years from Earth.
About 37 years.
