A moon page is fields more than prose. Parent planet, mean radius, orbital period, semi-major axis, eccentricity, inclination, discovery year, discoverer, group (Galilean, Inuit, Norse, and so on), and notes on surface features or atmosphere. The values vary per moon, the shape does not. Hand-built satellite pages drift fast: groups get inconsistent labels, radii mix km with Earth-moon radii, and discoverers sometimes appear with affiliation and sometimes without.

SleekRank reads a satellite sheet (Google Sheets or CSV, optionally seeded from JPL Solar System Dynamics exports) and renders one URL per row at /moons/{slug}/ using a base WordPress page as the template. Parent body, radius, orbital period, and group slot into fixed selector targets via mappings. Notable features render as lists. Update the sheet, clear the cache, and every page reflects the new data.

The sample table shows the pattern: io (parent Jupiter, 1,821 km radius, 1.77 d, Galilean), europa (parent Jupiter, 1,560 km, 3.55 d, Galilean), titan (parent Saturn, 2,575 km, 15.95 d, prograde), triton (parent Neptune, 1,353 km, -5.88 d retrograde, irregular), and charon (parent Pluto, 606 km, 6.39 d, regular). Each row carries its own context.

Moons are catalog entries with strict fields. Parent body is a category. Radius is a number with a unit.

Orbital period is a duration, sometimes negative for retrograde orbits. Group is a controlled vocabulary tied to discovery clusters and orbital character. Treating each moon as a freeform post lets group labels drift, units mix, and retrograde signs disappear.

With SleekRank, layout stays uniform because every page reads the same fields. When the IAU confirms ten new Saturnian irregular satellites in a single announcement, the editor adds rows to the sheet, the cache flushes, and the new pages ship in minutes. Per-moon URLs become reliable deep-link targets for mission articles, planetary-science courses, and parent-planet hub pages.
