I love Pluto! Still a planet to me.
You can see the images of Pluto sent back by the New Horizons mission, launched in 2006 and passing Pluto in 2015. Of course, this was a fly-by, if we had wanted to put the spacecraft into orbit then the journey would have taken much longer.
I sometimes describe Fly-By missions as: “have you ever been on holiday, and you want to see as many sights as possible, so your parent won’t even stop the car and just tells you to take a picture so you can get on to the next destination?”
