Binary Star
The discovery of a fully typographical star system comes with a big asterisk.
Title text: The discovery of a fully typographical star system comes with a big asterisk.

Explanation[edit]

Binary star systems, where two stars orbit each other, are common throughout the universe. In some cases, these are different types of stars, such as a neutron star orbiting a main sequence star. Here, however, the comic depicts a system consisting of a real celestial object (a main sequence star), and a star which has a stylised five-pointed shape in which stars are often drawn, called a pentagram.

Pointed stars do not actually exist as astronomical bodies.[citation needed] Stars seen in the night sky can sometimes appear as though they have spikes coming out of them, but these are just optical illusions caused by the diffraction spike effect.

The title text puns on the * symbol (an asterisk - meaning little star), which is sometimes called a star, and is often used to indicate footnotes in text. A "big asterisk" is used as a metaphor for a rather large caveat or significant reservations about the statement being made, suggesting that such qualifications would form a long footnote. This could be interpreted as meaning that the existence of the "typographical star system" is significantly doubtful. Alternatively, it could be read as meaning that the "big asterisk" is a physically very large (astronomical scale) punctuation symbol, which forms part of a system composed of other bodies in the form of typography.

Drawing a star as a pentagram, as shown in the comic, is referenced in 1029: Drawing Stars.

The orbital paths shown are anomalous. The main sequence star follows a path that's nearly circular, while the five-pointed star follows an elliptical path, and they're at different locations along their paths. If the two stars were the most massive objects in their system by a significant margin, approximating a two-body system, their paths should be the same shape (albeit at different sizes, if their masses differ) and their locations along those paths should be in phase. This implies that there's at least one other massive object in the system, which isn't shown. The much smaller path of the main sequence star suggests that it's in a (relatively) close orbit with the other massive object, with the five-pointed star being much less massive than either, and essentially orbiting them at a greater distance.

[Graphical depiction of a binary star system. The orbits are shown with dashed lines. One star is revolving circularly close to the center of mass and is shown as a filled circle. The other has a very elliptic orbit further out. It is currently close to its furthest point from the other star. This star is depicted as a pentagram.]

Randall has been, uh, funnier… I thought I must be missing something, a clever joke or some astronomers insider, but no—that's really all there was to it. Well. 2a02:908:c30:5000:b86c:d747:e182:c327 (talk) 07:54, 5 February 2026 (UTC) (please sign your comments with ~~~~)

Nice to see that Randall has graduated from the woes of 1029, and now can draw Morocco-style stars :-) --2001:A62:5F7:FB01:BF80:8165:D7C9:B014 08:24, 5 February 2026 (UTC)

The idea of pointed stars alongside normal ones is probably a reference to the James Web Space Telescope. In its images, very bright stars have diffraction spikes, caused by the segmented hexagonal primary mirrors and the three-strut support of the secondary mirror. However, these form 8 spiked images not 5. The Hubble Space Telescope forms 4 spike images, however the effect was not so noticeable with Hubble. 2A12:F41:145B:1300:C59:505F:B2DB:7572 12:19, 5 February 2026 (UTC) dww-uk
