I didn't post the comment in question, but I'm sure they meant nose. Look at the top of the screen where a maximized window's menu bar is located. Notice where your nose is located. Next look at the bottom of the screen where the taskbar is located, and notice where your nose is located. Most likely your head moved a little and therefore your nose moved.
Next look at the top of the screen and then without moving your head, look at the taskbar. You can do it, but try it several times and it will probably start to feel a little weird. Your head is likely to want to move a bit, and holding it still takes effort.
Instead of geostationary, I think you mean low earth orbit (LEO). There is a link to the Wikipedia article on LEO in an adjacent comment. A circular geostationary orbit is at an altitude of 22,236 miles/35,786 kilometers.

YMMV.
