Question

2D

I want to make a planet in 2D style, I understand how to draw pixel graphics and what programs are needed for it, but in pixel graphics the corners turn out to be sharp, pixels. And I need to draw a smooth, even surface.

read this article for example.
In fact, you just need to draw with a higher resolution so that it is not noticeable, the screen is still in pixels, even though you will make an almost perfectly round plane out of polygons there..
