1964: Spatial Orientation - Revision history

172.70.90.92: /* Explanation */ Proper name for Earth, Moon, Sun. Leaving/clarifying "ful ..." and "new moon"s, plus sunrise (as events). Converting URL-link to wikipedia into 'nicer' template-link for same (the edit that I came here for, before noticing the rest...)

 The Earth's orbit around the sun is counter-clockwise, when viewed from above the North Pole looking down. Earth's counterclockwise orbit around the sun means that, for most latitudes, the direction the Earth is moving around the sun corresponds roughly to west at noon, and east in the middle of the night. The Earth is spinning, so "east" from any given location on the surface is not always the same direction relative to the sun.
-The speed of the Earth's orbit around the sun depends on the time of year. The Earth moves faster around the sun when it is closest to the sun in early January, and slower when it is far away in early July (which may be counterintuitive to those in the northern hemisphere). However, Earth's average orbital speed is reportedly about 29.78 kilometers per second, with Earth's average distance from the sun being a bit less than 150 million kilometers. Earth's orbit around the sun is nearly circular, with an eccentricity of just 0.0167.

 If it is not a solstice day, or if it is not noon, the calculations could become more complicated. The comic was uploaded roughly two weeks before the northern hemisphere’s spring equinox. Cueball notices that the sun is “passing over his left shoulder” as he faces west. At temperate latitudes in the northern hemisphere, the sun would be to the left of a person facing west around midday almost any time of year, although how many degrees to the left depends on the calculations discussed above.
-An easier way to identify a line that is aligned with the solar plane would be to simply point directly at the sun (without hurting his eyes). Since the distance between Cueball and the center of the Earth is minuscule compared to the distance between the Earth and the Sun, if he simply points directly at the Sun (preferably without looking directly at it), his arm and finger will be pointing in a direction that is basically perpendicular to the line connecting the Earth and Sun, which obviously lies on the plane of the Earth's orbit. The Earth's position will have changed minimally in the eight minutes it took the sun's light to reach earth, so the apparent direction to the sun matches the actual direction. However, this will only provide one line that lies on the plane of the solar system and a line is insufficient to uniquely identify a plane.
