The constellation Ursa Major (the Great Bear) is not made up of a fixed number of stars. It's a pattern we see in the sky, and the number of stars we consider part of that pattern varies depending on how we define it.

Here's a breakdown:

* The Big Dipper: The most recognizable part of Ursa Major, the Big Dipper, is made up of 7 bright stars. These are often considered the most prominent stars in Ursa Major.

* Full Constellation: When you consider the entire constellation of Ursa Major, including fainter stars, it can encompass hundreds of stars. However, these fainter stars are often not visually connected to the Big Dipper, making them less prominent.

So, the answer depends on how you define the constellation. The Big Dipper has 7 main stars, but the full constellation of Ursa Major can contain many more.
