<p>Looks like your best bet is to study engineering physics with a concentration in aerospace and perhaps adding a minor in astronomy. As an example, here are some programs from my own school:</p>

[The</a> Astronomy and Astrophysics Minor at Ohio State | Department of Astronomy](<a href=“http://astronomy.osu.edu/Major/minor]The”>http://astronomy.osu.edu/Major/minor)</p>
<p>But to really “do” astrophysics you need a PhD. They don’t even teach general relativity at the undergraduate level. If you’re lucky there might be a short elective course offered sporadically, but at just about every university they reserve general relativity for the graduate level because of the mathematical preparation required.</p>
