Why is longitude on Mars measured 360 degrees all the way around, going
west, instead of like on Earth where we have two zones of 180 degrees
each, going both east and west? Why don't we uniformize these systems?
[snip]
Selenographic and lunar coordinates on the Moon work like
latitude and longitude on maps of the Earth. This makes since because
the Moon always presents the same face to the Earth with the zero
point more or less in the middle of the disk.
So what defines 0° longitude on Mars?
