Earth Gazing

I have a question that I have asked several people and can’t seem to get an answer for.

If you were standing on the moon and looked back (up?) at Earth, which direction would the continents be pointing? For example, If Africa and Europe was visible, at the time you were viewing Earth would the tip of South Africa be pointing up or off to the left…etc. ? Would this change depending on where you were standing on the moon?

Thanks for an intelligent answer for probably a stupid question.

Yes. By choosing the place where you are on the moon, you can choose your orientation with respect to the earth.

For an analogy, right now I’m in New Zealand. It’s a clear night and I have a beautiful view of Orion, who is standing upside down (e.g., his dagger points up from his belt).

Here is what the Earth looks like from the Moon during the “full Earth” phase. Yes, the Earth goes through phases as seen from the Moon just as the Moon goes through phases as seen from Earth. However, If you are on the other side of the Moon, you will never get a view of Earth.

It depends entirely on your location on the moon, just as the apparent orientation of the moon depends on your viewpoint from Earth.

Here is the Photo taken from the moon called Earthrise, Not sure if its much help, but its a way cool picture :cool:

Of course, you could just lie on the ground and view the earth from a “backflip” position. Or on your side. Or whatever.

To be a little more specific, if you were standing near the Moon’s “North Pole”, you would see the Earth near the southern horizon and it would appear “right side up”, i.e., Earth’s North Pole would be more or less at the top.

If you were standing near the Moon’s “South Pole”, you would be looking at Earth near the Moon’s northern horizon, and you would see it “upside down”, with Antarctica on top.

If you were standing near the Moon’s equator, and far to the east (or west) of the point we see as the center of the Moon’s disk, you would see Earth lying on its side.

Note that in no location would you see Earth actually rise. It would remain in basically the same spot in the sky at all times. You would, however, see it turn on its axis and be able to watch all the continents pass by.

From the far side of the Moon, you wouldn’t see the Earth at all, ever.

Mostly true. But the Moon doesn’t quite always turn exactly the same face to the Earth (this is called libration), so from a point near the “edge” of the Moon, the Earth would rise and set slightly above and below the horizon.
