Latvia post issued a stamp block consisting 12 different stamps dedicated to Zodiacs Constellations, which displays the journey of the Sun.
Zodiacal constellations in astronomy are a way of displaying the journey of the Sun across the vault of heaven.
The Zodiac is the ring of constellations that the Sun seems to pass through each year as the Earth orbits around it.
Astrologically, each zodiacal sign comprises a 30 degree arc, while the 12 signs together make a circle of 360 degrees or a cycle of one astronomical year.
The Zodiac is also a point of reference for the observation of the Moon and planets in the sky, because they move along the zodiacal constellations.
Essentially, the zodiac is a celestial coordinate system, or more specifically an ecliptic coordinate system, which takes the ecliptic as the origin of latitude, and the position of the Sun at vernal equinox as the origin of longitude.
The 12 Zodiac signs are: Capricorn, Aquarius, Pisces, Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, and Sagittarius.
