Zodiac in the Sky

Up until this point I did not quite understand how exactly the zodiac signs were defined by the stars. The zodiac is the section of the sky in which we find the Sun, Moon and the planets, except the planet Pluto (which technically doesn't count now either) because the planet was not discovered until afterwards.

The zodiac span is sixteen degrees wide, and extends about eight degrees north and south of what's called the ecliptic. These signs are defined by seasons and when the Sun is right over the Earth's equator (the March equinox) this is the first sign of Aries. About three months later the Sun on the June solstice reaches its northernmost declination for the year making it the tropic of Cancer.
Six months after March equinox (called the September equinox) the sun's position makes it the first point of Libra. Toward the end of the year, the Sun reaches its southernmost declination at the tropic of Capricorn (the best sign in MY personal opinion) during the December solstice.

The March equinox Sun has shifted about thirty degrees westward through the constellations of the zodiac. During this present time, the Sun will be at the first point of Aries on the March equinox, but the stars of the constellation Pisces backdrop the March equinox Sun. At the June solstice, the Sun stands at the tropic of Cancer but in front of the constellation Taurus. On the September equinox, the sun resides at the first point of Libra but in front of the constellation Virgo; on the December solstice, the Sun stands at the tropic of Capricorn but in front of the constellation Sagittarius.

Interesting eh?
