The two stars in the Big Dipper that help locate Polaris are called the Pointer Stars, and they are crucial for navigation. The Big Dipper is a well-known group of stars in the constellation Ursa Major. Two stars at the edge of its “bowl” point almost directly towards Polaris, the North Star.

Polaris is important because it is nearly fixed in the sky above the North Pole, making it a reliable guide for direction in the Northern Hemisphere. By following the line from the Pointer Stars, observers can find Polaris easily even without a compass.

The Pointer Stars are named Dubhe and Merak. Their brightness and position make them easy to spot on clear nights. This simple star-hopping method has been used by sailors and travelers for centuries to find their way.

The other options are incorrect:
- “The North Seekers” and “The Pointer Sisters” are not actual star names.
- “None of these” is obviously not the correct answer.

In summary, the two stars called the Pointer Stars in the Big Dipper guide us to Polaris, making them vital for star navigation.
