Early this morning going out on the balcony, I looked up on a star chart app to verify it was Jupiter I was seeing. Then I noticed the alignment of Mars, Saturn, and Pluto on the app.
Never being able to identify it before, I stared at where Pluto should be and I'm pretty sure I saw it.
My only question is - since it's said that planets shine and stars twinkle, it did seem that Pluto was flicking a bit. Is this normal?  Something to do with the relatively low luminosity and greater length of space?

Pluto is something like magnitude 14. The limit for the human vision is somewhere between magnitude 6 (widely accepted) and 8-ish (highly trained observers with perfect vision in ideal conditions using special techniques - and it's a bit controversial anyway).

There's zero chance that was Pluto. It was definitely a fixed star.
