The distance between Polaris (North Star) and Earth is approximately 433 light-years, which is about 4.086 × 10^18 meters. This distance is constantly changing due to the movement of both Earth and the star.

The absolute magnitude of Polaris is about -3.64. This value represents the intrinsic brightness of the star if it were observed from a standard distance of 32.6 light-years.
Polaris is a Cepheid variable star 430 light years away. It has about five times the Sun's mass and has a diameter more than 40 times greater than the Sun's. Because it's an aged star fusing heavier elements for energy, it's luminosity is very high, some 2,000 times that of the Sun. That is why it shines at 2nd magnitude in our skies even though it's about the same distance from us as the Pleiades. This star is also a triple star, the distant companion being visible in small telescopes and the closer one only detectable with adaptive optics or spectroscopy
Polaris (North Star or Pole Star) has an apparent magnitude of +1.97 (Variable)

Also known as Delta Ursae Minoris, Yildun is a white A-type main sequence dwarf.
The star Yildun is classified as a white star, which means it emits a white light. White stars are typically hotter than other stars like red or yellow stars.
The current north star, known as Polaris, has a distance estimated at 325-425 light-years. From Wikipedia: "Many recent papers calculate the distance to Polaris at about 434 light-years ... Some suggest it may be 30% closer ..."

Polaris, also known as the North Star, is approximately 433 light-years away from Earth. Its distance is often measured in light-years, which is the distance light travels in one year, about 5.88 trillion miles (9.46 trillion kilometers). Polaris is located in the constellation Ursa Minor and serves as a key navigational star due to its position nearly aligned with the Earth's rotational axis.
Polaris, also known as the North Star, is located about 433 light-years away from Earth, while the constellation Gemini is not a single point in space but rather a region of the sky that contains multiple stars. The distance to the stars within Gemini varies, with some stars being significantly closer or farther from Earth than Polaris. Therefore, the distance between Polaris and the stars in Gemini can vary widely depending on which specific stars are considered.
The stars in the Little Dipper, part of the Ursa Minor constellation, are at varying distances from Earth, ranging from about 48 light-years (for Polaris, the North Star) to over 300 light-years for other stars in the asterism. The distances between individual stars in the Little Dipper are not uniform and can be quite vast, often exceeding several dozen light-years. For example, the closest pair of stars, Polaris and Kochab, are approximately 48 light-years and 130 light-years from us, making the distance between them roughly 82 light-years. Overall, the distances between stars can significantly vary, reflecting their unique positions in our galaxy.
