You can zoom out from a craft to the solar sytem and beyond (interstellar is on the roadmap), and it's completely smooth and seamless 
Also, I love the cat theme, but I'm very divided if I can ever stomach launching a mission with a crew based on my IRL cats 
Bold of you to assume I am not too stupid for orbital mechanics
Once you internalize orbiting as falling sideways so fast you miss the ground, you get to say you’re a rocket scientist.
Serious answer: Scott Manley's tutorials are a good resource for getting started. If I can figure it out, anyone can!
Also serious answer: repeaditly flying ballistic trajectories into Tel Aviv is always a valid way to play.
Orbiting is pretty straightforward, so is transferring to a moon or something. Planets are tougher because both are moving instead of one orbiting the other. You need to speed up to go somewhere and you need to slow down to stop there. That's about the gist.
Orbiting is easy. Orbiting from one planet to another is also easy if you think of it like firing a gun with a curved trajectory that needs to hit another moving object that is travelling on its own curved trajectory at 87,000km/h
Speed up makes your circle bigger, slow down makes your circle smaller. Try not to miss.
