You're asking about the magnitudes of the stars in Ursa Major (the Great Bear). Here's a breakdown:

* Magnitude: Magnitude is a measure of a star's brightness as seen from Earth. Lower magnitudes mean brighter stars.

* Ursa Major's Main Stars: The Big Dipper, which is part of Ursa Major, has seven prominent stars:

* Dubhe (α Ursae Majoris): Magnitude 1.81 (brighter)

* Merak (β Ursae Majoris): Magnitude 2.37

* Phecda (γ Ursae Majoris): Magnitude 2.44

* Megrez (δ Ursae Majoris): Magnitude 3.32

* Alioth (ε Ursae Majoris): Magnitude 1.76

* Mizar (ζ Ursae Majoris): Magnitude 2.23 (has a companion, Alcor, with a magnitude of 4.0)

* Alkaid (η Ursae Majoris): Magnitude 1.85

* Other Stars in Ursa Major: Ursa Major has many other stars, some fainter than those in the Big Dipper. The brightest of these is Talitha (ι Ursae Majoris) with a magnitude of 3.11.

Remember: The apparent brightness of stars can be influenced by factors like distance and interstellar dust, so these magnitudes are just approximations.
