These are always illustrations based on whatever data we could gather. We almost never "see" the planets themselves.

Considering we only know it's there because it slightly dims the light from its star as it crosses during its orbit, you would be correct. At that distance, we would never see light bouncing off the actual planet. Even the star is basically a single pixel. We can estimate its size and orbit based on how quickly it crosses in front of the star and how much the light dims, and using those two numbers we can estimate its distance from Kepler 452.

lol. All those flyby probes we've sent to other planets in the system and we could've just pointed our interstellar telescope instead and looked for puddles.

Soon, though, using gravitational lensing of the sun. Sometime around 2035 maybe.

You know that picture we have of the milky way?

It's called Project Hail Mary you ding dong! We sent someone there in a last ditch effort to save the Earth!
