You’re trying to build your list from the top down (i.e. starting with the most competitive possible schools) which is a recipe for stress and disappointment. Super-reach schools are easy to identify. Start by looking for safety and match schools that you could be happy with.
What’s your home state? What honors programs are available at your state flagship?
You haven’t mentioned your financial circumstances. Could your family even afford a school like MIT? Are you eligible for financial aid, or would you need to pay full price at a private university that doesn’t offer merit aid?
There are all sorts of schools that are highly-regarded for physics and astronomy/astrophysics, without being insanely difficult to get into. Consider, as just one example, the Honors College at UCF For Those Who Dream of Space, UCF is the Place . In the category of competitive but not MIT-level competitive, look at Smith College, which has a terrific reputation for STEM including physics, and also has cross-registration with the rest of the 5-College Consortium… and Reed College in Portland, which produces a disproportionate number of future PhD’s for its size, in a variety of fields including physics. In fact, this list of PhD-producing institutions could be a great place to get ideas: Top Feeders to Ph.D. Programs Of course, it includes tippy-top schools like MIT and Caltech, but it also includes others that may surprise you.
Certainly, have some reach schools on your list. But think about what kind of experience you’re looking for as an undergraduate, and find less competitive schools where you could be happy, as well. The career you’re aiming for will require grad school, if you stay on that path, so play the long game and aim to end up in a top grad program, with as little student debt from undergrad as possible. You can accomplish this from many, many places, so think about what kind of environment would work best for you and allow you to thrive.
