The reason why each planet's circular border appears straight is because it's such a small area of each planet: you're only seeing a couple of square inches of the surface of each of the planets, and even though they are all round, the curvature would be imperceptible on this scale. The four gas giants are completely smooth, whereas the four rocky planets display features, most notably on Earth where grass and an ant are visible. | The reason why each planet's circular border appears straight is because it's such a small area of each planet: you're only seeing a couple of square inches of the surface of each of the planets, and even though they are all round, the curvature would be imperceptible on this scale.

| − | That it cannot have been an image of the real planets aligning is clear, as Mercury can be shown to be in front of Jupiter (implying that the latter is in the part of its orbit on the far side of the Sun from the viewer), yet Jupiter obscures Earth (which necessitates that it be in the arc of orbit ''nearest'' any given observer) | + | That it cannot have been an image of the real planets aligning is clear, as Mercury can be shown to be in front of Jupiter (implying that the latter is in the part of its orbit on the far side of the Sun from the viewer), yet Jupiter obscures Earth (which necessitates that it be in the arc of orbit ''nearest'' any given observer). In the title text it is made clear that this is just a small part of a larger drawing, so this is not an image taken from far away – they are only placed this way for scale. |
The title text remarks that it is hard to find a display that supports a version of the image without cropping. This is because a true 1:1 scale image showing all of the planets would be at least as big as the largest one, Jupiter – far larger than any monitor or display currently available{{Citation needed}} – or perhaps even big enough to hold Saturn's rings, in whatever orientation they lie. Furthermore, the amount of video memory that a graphics card would need to have in order to output at anywhere near the same {{w|Dots per inch|DPI}} to such a display, even as a 1-bit-per-pixel-image (i.e., all pixels are either black or white), is well beyond the capabilities of any graphic card that existed at the time of publication.{{cn}} | The title text remarks that it is hard to find a display that supports a version of the image without cropping.
