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.

Explanation:
The greatest obstacle when moving from the fossil fuel to renewable energy is that of economic costs, as green or clean energy is reusable technology.
Availability of infrastructure is needed for the make more energy for the natural resources as compared to the fossil fuels are more easily to extract as compared to building solar and wind farms.
Like coals and natural gas accounts for 30 to 35 % of the market share as compared to the hydropower and other renewables.
