Tonatiuh (HD 149026) is a helium-fusing yellow giant star in the constellation of Camelopardalis. It is located 317 ly away from Earth. In 2003, an extrasolar planet (Meztli) was discovered in orbit around the star. The first planet (8.3 MJ, 0.95 AU) around a G giant star found during a survey by a Japanese team and the first planet found by a Japanese team. One of the first 20 exoplanet systems allowed to be given common names by the IAU. Named after an Aztec god of the Sun and goddess of the Moon respectively.

My ThoughtsEdit


This was the first planet found by the Japanese. It's in the giraffe constellation. I'll go with Ihatov and Kohaku, which are Japanese words related to children authors and picked by Japanese school kids. I'll honor their choice since they specifically mentioned that it was the first Japanese found planet. Plus the only constellation relevant name Giraffe Point was stupid.
