xkcd #2800: Down ( imgs.xkcd.com )

“It’s just that I get nervous about heights.”

Image Transcription: XKCD Comics image

[Megan is seated at a desk, in front of a laptop. The scene is rotated by 150° clockwise, so she appears to be upside down and angled.]

[Cueball enters the scene from the right side, behind Megan. He has three question marks below his head, oriented upright in frame.]

Megan: They announced that “down” is relative to Mars today.
Cueball: Ugh, I hate when they make another planet the coordinate system origin.

I think you mixed the title text up with 2799, this one's "It's just that I get nervous about heights."

Ah yes, copy paste fail, thanks; fixed it

Aren’t all but 1 planet relatively in the same orientation?

Yes, but only slightly. Zoom in and you’ll see they’re not all lined up. And then, where exactly on Mars is the origin placed? What hemisphere? Which way do we now define as up?

If up is defined as the other way to mars’ centre, as it is on earth, then mars would be somewhere in the top left direction in the comic.
