Question

The Earth's precession has caused the North Pole to point to other stars besides Polaris in the past

Answer 1

Answer:

True

Explanation:

• The spinning of the earth on its axis has led to the stars to travel across the sky in a circular direction, as when you reach the north pole the stars appear directly above us as the atmosphere is less dense and more clear.

• This is defined as the axial precession is slow, gravity-induced and changes in the order of astronomical body rotation. Also known as the precession of the equinoxes, discovered in 1929.

• Polaris being a north pole star, the brightest star in the constellation. Standing almost motionless in the northern hemisphere. And s about 433 light-years away from being a yellow supergiant it's in precession with that of earth. It is 2.5 brighter than today as in Ptolemy time.
