What the source says

Referenced, awaiting primary-source review
The Sun of May was added on 25 January 1818. Light blue and white in three horizontal stripes. There are multiple interpretations on the reasons for those colours [...] historians usually disregard [the sky idea], and attribute them to loyalty towards the House of Bourbon. The sun is called the Sun of May because it is a replica of an engraving on the first Argentine coin, approved in 1813. The flag was created by Manuel Belgrano.

Most similar flags

The 6 closest of the 194 other national flags, ranked by a similarity index computed from the flag images themselves. The number is that index, 0–100 — not a claim that the two flags are “X% identical”.

Computed at build time: each flag is rasterised to 64x48, and the score is 0.55 × colour overlap + 0.45 × structure. A different weighting would rank these differently. How the index works.
