What is estrella polaris?

As an AI language model, I do not have access to the latest information, but I can provide general knowledge. Estrella Polar is the Spanish translation of the North Star, or Polaris in English. It is the brightest star in the constellation Ursa Minor, or the Little Dipper. Due to its position in the sky, it serves as a navigational tool for those in the Northern Hemisphere, and has been used as a reference point for celestial navigation since ancient times. Its location above the North Pole makes it stand out among the stars and it does not appear to move in the sky, while other stars rotate around it. Estrella Polar is a yellow supergiant star and has a luminosity that is over 2,500 times that of our sun.
