Definitely not possible- you would not have enough room in your schedule to even accommodate Astro and MSS together. Usually those who double major do combinations that are much closer in subject matter (ex: management and economics), and they are generally people who validated a significant number of the core courses to make this possible.
As far as a language minor goes, that's doable- but VERY difficult with Astro. A 2015 grad that I knew majored in Astro with a minor in Chinese, but he often had semesters with 7 or 8 classes. As you can imagine, he was usually hard at work. Other majors (such as Political Science, Foreign Area Studies, etc.) allow a much better opportunity to minor in a language.
Bottom line: you will get the chance to see what major is for you over your first couple of semesters. Give it some time and don't lock yourself into one idea just yet, you may find you really enjoy a subject that you never would have thought interested you.
