:The diameter of Earth is ~12000km and distances are measured from the center of the object (that why there is a "Planet ruled out because I would be inside them" zone). I suppose Earth should be placed at a distance of 6000km instead of 12000k (as it is the radius, not the diameter that matter here).

This comic bothers me because the diagonal line with Earth on it cannot possibly represent what it claims.  Zero cannot be plotted on the X-axis with this log scale.  The entire "I would be inside of them" region is bogus.

Why is Earth's "Distance from me" 10000km? -- 19:26, 22 January 2016 (UTC)

The diameter of Earth is ~12000km and distances are measured from the center of the object (that why there is a "Planet ruled out because I would be inside them" zone). I suppose Earth should be placed at a distance of 6000km instead of 12000k (as it is the radius, not the diameter that matter here). 141.101.66.11 19:43, 22 January 2016 (UTC)
Earth's distance seems to be to the left of the 10Mm marker on the distance line, to me, although it's hard to tell without a straightedge. Remember the plot is diameter to distance. 108.162.238.71 19:52, 22 January 2016 (UTC)

This comic bothers me because the diagonal line with Earth on it cannot possibly represent what it claims. Zero cannot be plotted on the X-axis with this log scale. The entire "I would be inside of them" region is bogus.

Not if you're measuring to the center of the planet. 108.162.238.71 19:52, 22 January 2016 (UTC)
