Where is the Sun located in the Milky Way?

Where is the Sun located in the Milky Way? NASA/JPL-Caltech/R. Hurt (SSC/Caltech)

Not how far we are from the center, which we know pretty well now (about 26,700 light years), but how far we are from the midplane of the galaxy. Our Milky Way galaxy is a flat disk 100,000 light years or so across, but it's also about 1,000 light years thick. The actual thickness is hard to define, since the stars kinda fade away as you go up (or down) from the disk, like the Earth's atmosphere thins out as you increase altitude. Also, how thick it is depends on what you measure!
