Hey !
According to your query, you wanted to Know if aerospace engineering has something to do with Astronomy or not (like if aerospace engineering consists it or not ), NO aerospace engineering has nothing to do with Astronomy . Astronomy is the natural science discipline that focuses on studying space and celestial bodies such as stars, planets, meteors and galaxies, whereas Aerospace engineering draws upon our scientific knowledge of space to design, develop, manufacture and test technology used in flight or in space. As you have stated interest in Astronomy, better to pursue Bsc in physics or something of that kind rather than Aerospace Engineering.
Hope this helps
All the best !
