The {{w|Hertzsprung–Russell diagram}} is a scatterplot showing absolute luminosities of stars against its effective temperature or color. It's generally used to understand a star's age.

The axes are labeled in {{w|Kelvin}} (degrees {{w|Celsius}} above {{w|absolute zero}}) and, in a unlike many Hertzsprung–Russell diagrams, {{w|Watts}}. While most Hertzsprung–Russell diagrams are labelled in units of {{w|solar luminosity}} or {{w|absolute magnitude}}, all three are perfectly valid measures of {{w|luminosity}}, which refers to the total power emitted by the sun}}.

Regular Hertzsprung–Russell diagrams start at about 1000K and what is labeled on this diagram as 10<sup>21</sup> watts&mdash;i.e. the upper-left corner. This diagram has been extended to lower magnitudes on both axes. The joke comes from the absurdity of showing tiny (at least compared to stars) and often mundane objects on a diagram meant for stars.
