What are two characteristics that distinguish the star polaris from the star Aldebaran?

Answer 1

I suggest you look up each of the stars - for example on Wikipedia - and decide what characteristics you want to concentrate on. Two different stars may be different in the following characteristics: mass; diameter; color; surface temperature; distance from Earth; apparent brightness; absolute brightness; and several others.

Answer 2

Two characteristics that distinguish the star Polaris from the star Aldebaran are their brightness and their positions in the night sky.

1. Brightness: Polaris, also known as the North Star or Pole Star, is relatively bright and is the brightest star in the constellation Ursa Minor. It serves as a reliable navigational reference point due to its brightness and its position near the North Celestial Pole. On the other hand, Aldebaran, which is located in the constellation Taurus, is also a bright star but not as bright as Polaris.

2. Position in the night sky: Polaris is located very close to the North Celestial Pole, which means it appears almost stationary in the night sky as the Earth rotates. This makes it useful for navigation and finding the direction of true north. Aldebaran, on the other hand, is not located near any celestial pole and appears to move across the sky like other stars as the Earth rotates.

These two characteristics make Polaris and Aldebaran distinct from each other in terms of brightness and their positions in the night sky.
