it has a staggered orbit, covers all areas of the planet, but will be visible pretty often, maybe 25 times a year or so at a given point I am guessing. It appears as a fairly big star would but it does not twinkle (only reflecting the sun's light) , if you can pick it out on the horizon as soon as it appears (which is tough to do), it is in sight for only 5 or 6 minutes.
