<p>Since a Ph.D. takes at least 5 years, it is impossible to predict what the job market in astrophysics will be when you finish. Getting a B.S. in physics is a reasonable start, however, because it is possible to find jobs with that degree (not necessarily doing physics though) or change fields to any number of engineering disciplines for graduate school.</p>
<p>My advice to students who I advise is to choose a major you really enjoy and take advantage of all opportunities to get experience which will lead you toward the path you have chosen. If it is internships for an industrial position, or research for a graduate program. What you learn about “how to learn” in college can translate to many different careers.</p>
