Let’s consider an example with an imaginary planet. In this solar system, the planet completes one orbit around its sun in 8.6 solar days, instead of 365 days, as the Earth does. (I’m using a shorter year because it magnifies the difference between solar and stellar days, so you can see it more easily.)
Here is an animation showing the difference between solar and stellar days for this planet. The arrow shows when a certain spot on the planet points at a distant star (which would be way outside the frame) or at its sun. The instant when it points at the sun is when the sun would be at
