Rigel is imagined to be one of the feet of Orion, the Hunter.
That's the origin of its name "Rigel" . . . from the Sumerian/Hebrew/Arabic "regel" meaning 'foot'.

Betelgeuse is the brightest star in the constellation Orion However Betelgeuse is a cool red star that is 520 light years from Earth How can Betelgeuse look so bright if it is that far away?
It isn't the brightest star - at least, usually Rigel is brighter. However, Betelgeuse is variable, and can sometimes be brighter than Rigel. Wikipedia lists its luminosity as 105,000 times the luminosity of our Sun; and the distance, as 640 light years. Assuming these numbers, this would make it as bright as a star that is 10.5 times as bright as our Sun, at a distance of only 6.4 light years. In other words, the extreme luminosity compensates for its distance.
What constellation has 2 of the brightest stars in the sky?
Generally, stars are named with a Greek letter designating the relative brightness followed by the name of the constellation. "Alpha" and "Beta" are (generally) the two brightest stars. So the brightest star in the constellation Scorpio is "Alpha Scorpius". Most bright stars also have Arabic names; Alpha Scorpius is better known as Antares. This pattern doesn't ALWAYS hold; for example, the red giant star Betelgeuse is Alpha Orionis, while Rigel is Beta Orionis. But Rigel is brighter than Betelgeuse! The answer is that Betelgeuse is a somewhat-variable star, and when the stars were formally catalogued, was brighter than Rigel. Betelgeuse has since dimmed a little, and is now less bright that Rigel. Some astronomers use Betelgeuse's variability as a sign that it is nearing the end of its life, and will "soon" explode as a supernova. Of course, "soon" to an astronomer means "within the next 10,000 years or so".
