Hello student ,

Here I will suggest you to go according to your interest in particular field and if you are willing to pursue astronomy and scientist both then you can pursue for astrobiologist , which is an interdisciplinary’ field and sits as the Venn diagram overlap in the middle of many different kinds of science . For this you need minimum educational requirement which is a Bachelor's degree in any of the Science subjects like Space Science, Astronomy, Chemistry, Biology and any other appropriate science subject from a recognised university . But for now there is no scope in India because  it is a very new and upcoming field in India , but it is unique aprroach for a particular to pursue in other countries , and other country pays a lot for this .

Hope it will help you !

hey,

i hope you are well

so you want to go in field of astronomy but are not having good command on mathematics subject, i would not suggest you to go for same as physics and mathematics are prerequisite subjects , to be a scientist you must have a masters degree including physics and mathematics subjects necessarily. as you have also mentioned that your interest also lies in biology and why don't you opt biology and make your career in field of medical or microbiology which one you prefer more.

hope this helps

good luck!
