Alpha Ursae Majoris is brighter. It has a magnitude of 1.81 whereas, Epsilon Ursae Majoris has a magnitude of 1.76.
The greek letter A (alpha) comes before the Greek letter E (epsilon) in the Greek alphabet. Astronomers named stars according to their brightness. Starting with 'A' (alpha) being the brightest and (Omega) being the dimmest.
The brightest star in the Big Dipper is called Alioth. It is the fourth brightest star in the constellation Ursa Major.
The scientific name for the brightest star in Ursa Major is "Alpha Ursae Majoris," but it is more commonly referred to as "Dubhe."

Epsilon Ursae Majoris (Alioth) is the brightest star in the constellation Ursa Major.It is about 3.7 times larger than our Sun.
The brightest star in the Big Dipper is called Alioth. It is the fourth brightest star in the constellation Ursa Major.
Beta Ursae Majoris (Merak) is a star in the constellation of Ursa Major.It is about twice the size of our Sun.
Stars in a constellation or asterism generally share a perceived grouping in the night sky due to their proximity to each other. They may also share a similar brightness or color, making them visually appealing when viewed together. Additionally, they may have a cultural or mythological significance that ties them together in a specific grouping.
Neither. Epsilon Ursae Majoris (Alioth) is a white star, although it's spectrum is odd, implying that it has a mass about fifteen times the size of Jupiter orbiting it in a highly eccentric orbit.
The scientific name for the brightest star in Ursa Major is "Alpha Ursae Majoris," but it is more commonly referred to as "Dubhe."
Pointer stars are stars which are used to find an area of the sky. For example, you might be looking for a dim galaxy or small star. You can use two bright stars on a map, find those in the sky, and then find the approximate position of what you are trying to look at by using the location and spacing of the more obvious pointer stars.
47 Ursae Majoris is about 46 light years away.
