Hi, I'm a sophomore in college, but credit wise still a freshman I believe. I really love Astronomy and Physics but I'm just not much of a math guy. However I do really LOVE the science aspects of studying planets. I would love to study things such as the composition of planets when I get out of school, including our own planet. But I'd also really like to be able to for instance study the proposed sub-surface oceans on Titan and other planets, and their moons, asteroids and so on (quite the ambitious, perhaps unrealistic expectations I know.) Considering that, would I be better off studying Environmental Science as a major while I'm in school, or should I major in Astronomy&Physics (they come together as a degree here)? Thanks so much for the help!
