Question

Ursa Minor contains the pole star, Polaris, and the asterism known as the Little Dipper. From most locations in the Northern Hemisphere, all of the stars in Ursa Minor are circumpolar. Does that mean these stars are also above the horizon during the day? Explain.

Answer 1

Circumpolar stars in Ursa Minor are always above the horizon but are not visible during the day due to the Sun's glare.

Step-by-step explanation:

Stars in Ursa Minor, including the pole star Polaris and the asterism known as the Little Dipper, are considered as circumpolar stars. This means that they are always above the horizon and do not dip below it. However, this does not necessarily mean that these stars are also above the horizon during the day.

During the daytime, the brightness of the Sun overwhelms the light from stars, making them invisible. The only exception is the Sun itself, which is visible during the day. Therefore, while circumpolar stars remain above the horizon at night, they are not visible during the day due to the Sun's glare.

Answer 2

Yes

Step-by-step explanation:

By definition, the circumpolar stars are those stars which neither rise nor set. They trace a complete circle around the pole star. That means they are always above the horizon. They might not be visible during the daytime because of Sunlight and atmosphere but that doesn't mean they are below the horizon. They will still be above the horizon but will be visible only during the night time.
