Astrology

Astrology is a pseudoscience that claims to divine information about human affairs and terrestrial events by studying the movements and relative positions of celestial objects.. Yes, the one whose famous books are Lal Kitaab and horoscopes

Ranking these on any basis could be biased but on my personal basis:

Aerospace Engineering ranks the topmost As it is primary field of engineering concerned with the development of aircraft and spacecraft. It has two major and overlapping branches: aeronautical engineering and astronautical engineering . Has practically more employability and scopes for growth.

Astrophysics/ Astronomy is a little on the off-side. It's just like doing a dedicated PhD in physics with (let's say) negligible pay and opportunities until and unless you are REALLY VERY ONE-TRACKED about it.

Astrology... well if you know about horoscopes, I need not say anymore.
