The host mentions three stars in a constellation which she says is called The Triangle, likely referring to the constellation {{w|Triangulum}}, which is in fact just three main stars in a narrow triangle. However, this may also simply be intended to show the host's lack of knowledge of constellations, since she then goes on to point out three other stars forming a triangle and concludes that one can form lots of triangles by connecting groups of three stars. In Euclidean and non-Euclidean geometry, any set of three non-collinear points will form a triangle, so to say that there are a "lotta triangles" is both trivial and an understatement.{{Citation needed}} (There are about 125 billion triangles visible in the night sky with around 9096 visible stars.) | The host mentions three stars in a constellation which she says is called The Triangle, likely referring to the constellation {{w|Triangulum}}, which is in fact just three main stars in a narrow triangle.

| − | Then she points to planets, calling them dots known as "fool's stars" (like fool's gold). Planets such as Venus and Jupiter are often mistaken as stars, and the word itself is derived from the Greek, ''planētēs'' or "wanderer." She also notes that lacking interstellar transportation, humanity will likely only reach the planets within our solar system. However, she then makes the seemingly ludicrous assertion that humans will turn these planets into interplanetary landfills, which might be a comment on how humans have used the Earth | + | Then she points to planets, calling them dots known as "fool's stars" (like fool's gold).

The host also notices a dot of "space trash": An artificial satellite. Since the nascent Space Age, the Earth's orbit has gradually accumulated artificial materials that include satellites, spent rockets, and space stations. There are concerns such debris accumulation will increasingly imperil current and future space projects. However, the host claims there is an app that can tell you "whose fault it is," presumably a satellite-tracking smartphone app such as [http://itunes.apple.com/us/app/skyview-satellite-guide-find/id694309958?mt=8 SkyView] which can inform you who launched a given satellite and thus whose "fault" that particular bit of space-junk might be. | The host also notices a dot of "space trash": An artificial satellite.
