The word “sun” occurs 103 times in Project Hail Mary.
It occurs in every one of the first 8 chapters (especially chapters 3 and 5) but usage begins to fade with only 6 occurrences in the second half of the book. It is not mentioned at all between chapters 20 and 28 but does return in the final two chapters.
It is used 60 times in Earth sections: 17 times by the narrator, 3 times by Bob Redell, 20 times by Grace, 6 times by Marissa, 9 times by Stratt, and 1 time by each of Abby, Dr Browne, Larry, Michael, and Sandra Elias.
It is used 43 times in Space sections, all by the narrator.
Here’s a visualization of the relative frequencies across all sections and chapters of the book.
Each coloured bar represents a section and is colour-coded for Earth sections (green) and Space sections (purple).
The grey bars represent the chapters, which are marked with ticks and numbers.
The y-axis is the relative frequency, i.e. the proportion of tokens in that section (or chapter) that match “sun” (so a bar might be higher, even with fewer occurrences, if the section or chapter is shorter).
The sun part was pretty easy
