Rigel and Betelgeuse don't orbit each other. They are hundreds of light-years away from each other.
Rigel is beta Orion so I am not sure what the question is about.
Answer When Bayer prepared his catalogue, there was no way to measure stellar brightness precisely. Traditionally, the stars were assigned to one of six magnitude classes, and Bayer's catalog lists all the first-magnitude stars, followed by all the second-magnitude stars, and so on. However within each magnitude class, there was no attempt to arrange stars by relative brightness. For example, in the Orion constellation, Bayer first designated the two 1st-magnitude stars, Betelgeuse and Rigel, as Alpha and Beta, with Betelgeuse (the shoulder) coming ahead of Rigel (the foot), even though the latter is the brighter.Also worth mentioningis that Betelgeuse is a semiregular variable star, and sometimes IS brighter than Rigel.So, it is possible that Betelgeuse was mistakenly classified as the brightest because it could have been experiencing an increase in brightness at that time.
That depends on what you want to call the 'beginning' of the moon's orbit.-- New Moon and Full Moon are opposite each other, 1/2 orbit apart.-- First Quarter and Last Quarter are opposite each other, 1/2 orbit apart.-- Each day of Waxing Crescent, and the Waning Gibbous that combines with itto form a complete disk, are opposite each other, 1/2 orbit apart.-- Each day of Waning Crescent, and the Waxing Gibbous that combines with itto form a complete disk, are opposite each other, 1/2 orbit apart.Hey! I just realized that every possible shape of the moon, and the shapethat combines with it to form a complete disk, are opposite each other,1/2 orbit apart.
So they don't run into each other.
No, most stars orbit the center of their galaxies. There are many types of star systems. For example, binary stars orbit each other.

They are both in the constellation Orion.

no because stars can orbit each other
Rigel is visible along with Orion. It can be seen in the mornings from August till October and in the evenings from November till January each year.
Each planet remains in orbit because of the pair of equal gravitational forces that attract it and the sun toward each other.

He discovered that avery planet has a ellipcial orbit, which means oval.
Yes, each of the 8 major planets has its own orbit, with no asteroids or other objects in its path.
So they don't run into each other.

Yes, and when they do so they are called binary stars (see wiki: http://simple.wikipedia.org/wiki/Binary_star) basically the two masses are attracted by each others' gravitational fields and orbit each other.
