The interior consists of three shells: the core, radiative region, and convective region. Image source: http://eclipse99.nasa.gov/pages/SunActiv.html. The core is the hot, dense central region in which the, the moon and the planets move: Ares (Ram), Taurus (Bull), Gemini (Twins), Cancer (Crab), Leo (Lion), Virgo (Virgin), Libra (Scales), Scorpio (Scorpion), (Sagittarius) Archer, (Capricorn) Sea Goat, (Aquarius) Water Carrier, and (Pisces) Fishes.
