Polaris

The apparent magnitude od the main star in the Polaris system is 1.98

The main star is the Polaris system is 7*10^7 years old.

43 degrees because the altitude of polaris is equal to the latitude of utica.

It is almost directly due North.

Polaris, also known as the North Star, is the final star in the handle of Ursa Minor, which is known as "The Little Dipper." It is easy to find because the two stars that make up the side of the bowl of Ursa Major that are not attached to its handle point directly to it.

No, Polaris is always in the same spot in the sky.

Almost directly above the North Pole.

The Big Dipper, or Ursa Major has two stars (sometimes called the pointer stars) which line up directly with Polaris. Those two stars, at the "lip" edge of the Big Dipper, are Dubhe and Merak. Merak is at the "bottom" of the Big Dipper, and Dubhe is right at the "lip".

No, Polaris (the North Star) is part of the Little Dipper (which is part of the constellation Ursa Minor, "The Little Bear"). Polaris is the bottom-most star in the "handle" of the Little Dipper.

Polaris is more commonly known as the North Star or Pole Star because its position in the northern night sky almost exactly marks the Earth's geographic north pole.

The apparent brightness of the main star in the system is 1.98 but remember that this is a Cepheid variable.

Polaris, the North Star, would only appear overhead if you were standing at the North Pole. From my location near Sacramento, CA, the star Polaris is visible about 40 degrees above the horizon, and is always in the same place. It does not appear to move.

Polaris is known by other names such as "pole star" or "North pole". Polaris has also been referred to as "Steadfast".

Your latitude!

The apparent daily movement of the stars in the sky is a reflection of Earth's rotation. Earth rotates around its axis; as a reflection of this, the entire sky rotates around an "axis", which is simply the extension of Earth's axis.

By chance, the star Polaris is almost exactly on the line of the Earth's axis, extended into space.

So, as the Earth rotates the stars appear to rotate around Polaris.

Circumpolar stars never go below the observer's horizon, so they just seem to go in circles around Polaris.

Ursa minor constellation

The altitude of Polaris, the North Star, closely corresponds to the latitude of the observer in the Northern Hemisphere. Specifically, if you measure the angle of Polaris above the horizon, that angle is equal to the observer's latitude. For example, at 40 degrees north latitude, Polaris will appear 40 degrees above the northern horizon. This relationship helps navigators and astronomers determine their latitude by observing Polaris.

The North Star, or Polaris, is located nearly at the celestial North Pole, making it a fixed point in the sky as other stars appear to rotate around it. It serves as a navigational reference for travelers in the Northern Hemisphere, as it indicates true north. Polaris is part of the Ursa Minor constellation and is approximately 433 light-years away from Earth. Its brightness and position have historically made it a crucial guide for navigation at sea and on land.

The altitude of Polaris, also known as the North Star, is directly related to the latitude of the observer in the northern hemisphere. Specifically, Polaris appears at an altitude equal to the observer's latitude; for example, if you are at 40 degrees north latitude, Polaris will be approximately 40 degrees above the northern horizon. This relationship occurs because Polaris is located nearly directly above the North Pole, making it a reliable indicator of latitude for navigation.
