Why would Polaris not always be north star?

Polaris, currently known as the North Star, is not always the North Star due to the precession of the Earth's axis. This slow wobble, caused by gravitational forces from the moon and sun, alters the orientation of Earth's axis over a cycle of approximately 26,000 years. As a result, the position of the North Celestial Pole shifts, meaning that other stars, such as Vega or Thuban, have served as the North Star at different points in history. Eventually, this cycle will lead to Polaris no longer being the North Star in the distant future.

What is one way that the sun and polaris are different?

One key difference between the Sun and Polaris is their role in our solar system and beyond. The Sun is a medium-sized star at the center of our solar system, providing light and heat essential for life on Earth. In contrast, Polaris, also known as the North Star, is a distant star located approximately 433 light-years away and serves as a navigational reference point in the night sky due to its position nearly aligned with Earth's rotational axis. Additionally, while the Sun has a significant influence on our planet's climate and ecosystem, Polaris has no direct impact on Earth beyond its visibility in the sky.

How many degrees above the northern horizon is polaris if you are at 34 Deg?

If you are at a latitude of 34 degrees north, Polaris, which is located nearly at the North Celestial Pole, will appear approximately 34 degrees above the northern horizon.
