I don't see the point of this debate on how the photo should be oriented. I can see the sun rise while sitting on a beach in Sydney. If I lie down, I will see it side on. If I take the photo while sitting up, the horizon will be shown as running right to left across the screen. If I lie down and take piccie, it will show horizon running up and down. What's the diff?

The idea for such a photograph seems to have came to one from a psychedelic state. I have read it in a quite-recent book about psychedelics, the title of which I cannot remember right now. If anyone gets more information about this, feel free to post more. [[User:Twipley|Twipley]] ([[User talk:Twipley|talk]]) 22:11, 7 January 2013 (UTC) |

light and dark
I dont know that much about space, but don't the light and dark side of the eart represent night and day in the course of 24 hours, instead of being similar to lunar phases? Could anybody who knows verify this? —Preceding unsigned comment added by 145.18.242.174 (talk) 15:44, 4 March 2008 (UTC)
- The light and dark side of the earth represent a earthican day as the earth rotates about itself relative to the sun. A lunar phase is exactly same as as the moon rotates about itself (and orbits the earth) relative to the sun. So while the moon always has one face to the earth, it still has night and day relative to the sun. njaard (talk) 00:34, 25 August 2008 (UTC)
What is the calculation used for the Lissajous figure that the Earth would "draw" above the Moon's surface? --Aewold (talk) 11:53, 22 October 2008 (UTC)
Laymen's Terms
Hi all. I would love to see the "Geometry of Earthrise" rewritten in a way to make it more accessible to the greater audience. Most of the terms there left me stymied. Cheers. Shiningheart (talk) 06:07, 24 December 2009 (UTC)
Geometry of Earthrise is Irrelevant
Apollo 8 was in orbit round the Moon, in the plane of the Earth-Moon system. That meant that they saw an "Earthrise" every orbit as they came around the Moon to the Earth-facing side.
The discussion of visibility of Earthrises from the Moon's surface is all very interesting, but it's not what was happening here.Steve Graham (talk) 16:44, 24 December 2009 (UTC)
- I was going to post the exact same comment, but since you already did I'll just say that I agree. If the article were about the general concept of the Earth rising over the Moon's horizon, it would be relevant. But this article, at least according to the note at the top, is supposed to be about a specific photograph that was taken from orbit. Still, the information is interesting and perhaps could be framed more explicitly as a digression. --Itub (talk) 17:13, 3 September 2010 (UTC)
Which Way is Up?
It's notable that the image is almost always shown rotated 90 degrees compared to how Anders framed and took it. As far as he was concerned, the spacecraft was orbiting around the "waist" of the Moon, and "up" and "down" were aligned with the Moon's axis.
Borman, however, framed his shots as though they were flying over the Moon's surface as in an aircraft. See http://www.abc.net.au/science/moon/earthrise.htm Steve Graham (talk) 16:44, 24 December 2009 (UTC)
