<p>There are degrees in astronomy but many astronomers have physics degrees. But there aren't a lot of positions going for professional astronomers (and those that are, you'd better be doing it for love, not money) so besides the degree, you're going to need to stand out from the crowd. </p>

<p>To get into scientific fields as a professional pretty much requires a doctorate these days.  This can be in astronomy or your chosen specialty (see below), but many are also in physics; what the subject is called may depend on the institution you attend to get the Ph.D.</p>

<p>Realize that what you and the general public thinks of as "Astronomy" is likely not the same as what the professional scientific world calls "Astronomy".

Someone who studies other planets is a "Planetary Scientist"; this can be further subdivided into "Atmospheric Scientist" (which can be even further divided into "Atmospheric Chemist", "Atmospheric Dynamicist", etc.) and "Planetary Geologist", and so on.  A scientist studying the origins of the universe is a "Cosmologist".  If you have a particular area you are interested in, research this to find out what you need to learn to move into that field.</p>

<p>Regardless of the degree you pursue, you will need a lot of mathematics and science.  During your undergraduate degree, I would recommend the following minimums: 3 semesters of Calculus, 1 semester of Ordinary Differential Equations, 1 semester of Linear Algebra (some schools combine ODE and LA), 3 semesters of Introductory Physics.  I'd recommend a semester or two of introductory astronomy, although some schools don't consider that as absolutely necessary, surprisingly. Other useful undergraduate courses will depend on what you think you will want to specialize in, but would include more physics, more astronomy, chemistry, geology, meteorology, etc.</p>

<p>If you aren't yet in college, take all the mathematics and physical science courses you can in high school... unless you're interested in becoming a astrobiologist (someone who studies living organisms on other planets - a speculative field at this point, but it does exist), in which case you should get some biology courses too!</p>

<p>Learning computer programming would be good also, as these fields often require programming for data processing and simulations.

I wouldn't define "an astronomer" as "someone who studies stars and groupings of stars", but more than "an observer", in opposition to "an astrophysicist" who is "a theoretician". I'm curious where your definition of an astronomer comes from, since it seems to me that the accepted meaning in the field is closer to what I just said.

@MBR: Perhaps it's a linguistic challenge, but your 1st sentence doesn't really make sense to me. The point of defining "Astronomer" as I did was to differentiate what much of the (American at least) public thinks of as a professional astronomer vs. professionals in the field.  This is based on my experiences (providing IT support) at a large scientific space exploration and astronomy institution.  My understanding of what you're saying is that there are no professional "astronomers".

Sorry, my comment was unclear. In your second paragraph, you say that an "Astronomer" is someone who studies stars and groups of stars. And then you give different names for different subtopics of the field. I would just say that "Astronomer" is a professional observer, whatever you observer (you can be an astronomer and work on galaxies, for example). The main distinction I tend to make in the field is Astronomer vs. Astrophysicist, and therefore "professional observer" vs. "theoretician". Then, there are different "flavors" of both astronomers and astrophysicists.

I think that closing the question rather than asking for clarification is plain wrong. You could simply point the OP to [Swinburne Astronomy Online](http://astronomy.swin.edu.au/sao/) or even [Galaxy Zoo](http://www.galaxyzoo.org/) and answer their question. In fact, almost every single "star tour" that I give people ask "How can I become an astronomer". The field is so broad, and there is so much work for amateurs to do, that you are doing the OP **and the community** a disservice by closing this common, valid question.

I'm closing this question since, well, it depends on what you mean by astronomer.  If you mean cutting edge researcher in astronomy, the path is pretty clear: get advanced degree(s).  On the other hand, I'd say that the first step toward becoming an astronomer is to go outside and look up at night.  I would label people who primarily teach the subject as astronomers.  But others would disagree.  Hence, "opinion based".
