If you were planning to travel in a futuristic spaceship to Betelguese, it would take over 640 years traveling at the speed of light. Describe the proprties (color, size, temperature, brightness) of Betelguse that you would expect to find when you come out of cryo-stasis.

Explanation:

We have never been able to travel close enough to Betelgeuse in order to be sure of its characteristics, but we have been able to get an idea from all of the information we have been able to gather using high-end equipment. Using this info we believe that Betelguese would have the following characteristics...

Color: a very deep red color

Size: about 950 times larger than the Sun in our solar system

Temperature: roughly 3,500 K which is close but not as hot as our Sun

Brightness: varying, since it is one of the brightest starts in our solar system (top 7) but it is continuously dimming.

These are rough estimates of what you can expect to find if you were able to travel close enough to Betelguese.
