<p>If you were going to major in physics, you’d just want to major in general physics. Engineering physics is a more specific track for people going into engineering. There would be a ton of courses that wouldn’t be related to a potential astronomy track at all.</p>
<p>Most schools don’t really offer any options in terms of undergrad physics majors. A handful of schools offer an astrophysics bachelors, but those are few and far between. </p>
<p>The thing to keep in mind, is that you’d likely have a little catching up to do during the first year or two of grad school if you majored in math. You’d be missing some of the required physics courses like the upper level mechanics/E&M/quantum physics courses. You would likely get some exposure to them if you minored in physics, but not as much as a physics major would get.</p>
