Which star in Ursa Major points toward Polaris?

The star that points toward Polaris in the constellation Ursa Major is Merak. Merak is one of the two stars that make up the "Pointer Stars" of the Big Dipper, which is part of Ursa Major. When you draw an imaginary line connecting Merak and Dubhe, the other Pointer Star, and extend it northward, this line leads directly to Polaris, also known as the North Star. Polaris is located in the constellation Ursa Minor and serves as a crucial navigation point in the northern hemisphere.

In this context, Dubhe is also a pointer star, but it is typically used in conjunction with Merak to locate Polaris. While Spica and Cas A are notable stars in their own right, neither is related to Ursa Major in the context of pointing to Polaris. Spica is located in the constellation Virgo, and Cas A is the remnant of a supernova located in the constellation Cassiopeia, making them irrelevant to this particular question focused on Ursa Major and its connection to Polaris.
