Unfortunately , we did not have enough info to make a ranking of the best colleges for non-traditional students studying planetary astronomy & science in the United States. This is typically due to there not being enough schools in the United States that both offer planetary astronomy & science and provided enough information for us to do a proper analysis.
One of 3 majors within the Astronomy & Astrophysics area of study, Planetary Astronomy & Science has other similar majors worth exploring.
