 *Kuiper gauntlet—this is a play on the {{w|Kuiper belt}}, which is a region of the Solar System beyond the planets, extending from the orbit of Neptune (at 30 AU) to approximately 50 AU from the Sun, notable for being full of asteroids; replacing the word "belt" with "{{w|gauntlet (glove)}}" (often spelled 'gantlet') which is a protective glove as well as "{{w|gauntlet (punishment)}}" which is a medieval punishment where one would be forced to run through two lines of men who would hit the punishee.
 *Oort void—refers to the {{w|Oort cloud}}, a gigantic "cloud" of materials (mainly composed of ice) which ends around a light-year from The Sun and is deemed the (current) "edge" of the solar system. The "void" may be pun on density of that "cloud" - the number of bodies in it may be huge, but given its size, it's mostly empty.
-*Crystal sphere holding the fixed stars—this refers to historical ideas about the universe, particularly the {{w|Ptolemaic system}}, in which the stars were supposed to be fixed on a {{w|Celestial spheres|large crystal sphere}} around the Earth. It might also be referencing "{{w|The Crystal Spheres}}", a short story by David Brin, in which humanity's first interstellar ship shatters a previously undetected, protective barrier around the solar system.  It may also be a reference to the Dungeons and Dragons setting "{{w|Spelljammer}}".

A crystal sphere around the solar system can also be seen in [[2765: Escape Speed]].
 *Total count above reaches 16 exits from the solar system vs. 22 in the comic itself.

 ''{{w|Voyager 1}}'' is a {{w|U.S.}} {{w|space probe}} launched in 1977 to study the outer reaches of the {{w|Solar System}} and beyond. Popular press has on several occasions announced that it "has left the solar system" at each point when a boundary has been confirmed or a major event has taken place. This underscores the fact that there is no strictly defined and recognizable boundary of the solar system, or at least we haven't found one yet.

 The chart shows that Voyager 1 has left the Solar System 22 times, but in the title text only 16 are mentioned.
