 Tiny objects smaller than 100&nbsp;m down to space dust are excluded altogether as explained in the note below the headings. This is probably because their total surface area is impossible to estimate accurately, and also because any estimate would likely be too large to fit easily into the map.

 Between Earth and Titan is a tiny speck noted ''all human skin'', which is an interesting sort of solid surface. A rough estimate of the average {{w|body surface area}} and thus of the average area of all {{w|Human skin|humans skin}} can be made from these {{w|Body surface area#Average values|average values}} and from {{w|Population pyramid|population pyramids}} as this [http://populationpyramid.net/world/2015/ pyramid for 2015]. Average adults have a skin area of around 1.7-1.8&nbsp;m<sup>2</sup>, but as a large part of the [https://www.census.gov/popclock/ human population] are children (with skin area down to about 0.25&nbsp;m<sup>2</sup> for infants) the total average will be smaller. By extrapolating the given values an average area of about 1.6&nbsp;m<sup>2</sup> can be found. This would make the area 7.2&nbsp;billion &times; 1.6&nbsp;m<sup>2</sup> ≈ 11,500&nbsp;km<sup>2</sup>. This is 60 times smaller than the smallest of the labeled moons {{w|Miranda (moon)|Miranda}} (of Uranus) with a surface area of 700,000&nbsp;km<sup>2</sup>.

 ===Title Text===
 The title text jokingly claims that this comic is not actually for information, but rather is something Randall thinks we should really do – that is, to stitch all the solar system's solid surfaces together, as the sub-sub heading says. To do this, we would need a giant spool of thread and then something he has to go get in Seattle… which presumably must be the {{w|Space Needle}}, a needle-like tower in Seattle, which should then be used in this grand project.

 ====Earth====
-On the area that signifies {{w|Earth}} the {{w|continents}} are drawn using a {{w|map projection}} that keeps the scale of the continents correct. (This is something that [[Randall]] cares about as can be seen in [[977: Map Projections]]). The parts of the surface of the Earth that are covered by oceans are also included in the surface area of the Earth (i.e. the map shows the Earth's {{w|Crust (geology)|crust}}). An extra layer of 3–4&nbsp;km of water seems rather insignificant when comparing to the Earth's radius of 6,370&nbsp;km.

 The objects mentioned by name on the map are all but one amongst those that have reached {{w|hydrostatic equilibrium}} and these are all included on this {{w|List of gravitationally rounded objects of the Solar System}}.
-The one named object that is '''not''' on the above list is the asteroid {{w|4 Vesta|Vesta}}, which is included because it is the second largest object in the {{w|Asteroid belt}}. It is placed right next to the largest object in this belt, the dwarf planet {{w|Ceres (dwarf planet)|Ceres}}, which is no longer considered an asteroid. [[acn]] And next to these two are the rest of the asteroids in two areas (see below), which thus groups all asteroids together.

 The only object from the above list, (that qualifies for having a solid surface in hydrostatic equilibrium), '''which is not included''' is the {{w|Saturn}} moon {{w|Mimas (moon)|Mimas}}, which is also clearly the smallest object on the list.
