@yukinoh1989 Indeed there is! With the object you want to smooth out, you’ll want to click on the “object” button at the top of the viewport (or bottom, if you swapped the header around):

After that you’ll want to select “Shade Smooth” and boom, you’re done. The only problem is that smooth shading requires more dense geometry so for most primitives it’ll look rather funky but it shouldn’t be too bad with the spheres.
