Twelve constellations along the eclipticPlane of Earth's orbit around the sun. All the planets except Mercury and Pluto have orbits in nearly the same plane. The Sun's axis is tilted at an angle of 7 °15' to the ecliptic, which has been proposed as evidence the Sun was originally part of a binary star system. through which the sunOur parent star. The structure of Sun's interior is the result of the hydrostatic equilibrium between gravity and the pressure of the gas. 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.
