The zodiac is a belt-shaped region of the sky that extends approximately 8° north and south of the ecliptic, the apparent path of the Sun across the celestial sphere over the course of the year. Also within this zodiac belt appear the Moon and the brightest planets, along the their orbital planes. The zodiac is divided along the ecliptic into 12 equal parts ("signs"), each occupying 30° of celestial longitude. These signs roughly correspond to the astronomical constellations with the following modern names: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces.
Brightness is an attribute of visual perception in which a source appears to be radiating or reflecting light. In other words, brightness is the perception elicited by the luminance of a visual target. The perception is not linear to luminance, and relies on the context of the viewing environment.
The swastika is an ancient religious and cultural symbol, predominantly found in various Eurasian cultures, as well as some African and American ones. In the West it is more widely recognized as a symbol of the German Nazi Party who appropriated it from Asian cultures starting in the early 20th century. The appropriation continues with its use by neo-Nazis around the world. The swastika never stopped being used as a symbol of divinity and spirituality in Indian religions, including Hinduism, Buddhism, and Jainism. It generally takes the form of a cross, the arms of which are of equal length and perpendicular to the adjacent arms, each bent midway at a right angle.
The caduceus is the staff carried by Hermes in Greek mythology and consequently by Hermes Trismegistus in Greco-Egyptian mythology. The same staff was borne by other heralds like Iris, the messenger of Hera. The short staff is entwined by two serpents, sometimes surmounted by wings. In Roman iconography, it was depicted being carried in the left hand of Mercury, the messenger of the gods.
A crescent shape is a symbol or emblem used to represent the lunar phase in the first quarter, or by extension a symbol representing the Moon itself.
Astronomical symbols are abstract pictorial symbols used to represent astronomical objects, theoretical constructs and observational events in European astronomy. The earliest forms of these symbols appear in Greek papyrus texts of late antiquity. The Byzantine codices in which many Greek papyrus texts were preserved continued and extended the inventory of astronomical symbols. New symbols have been invented to represent many planets and minor planets discovered in the 18th to the 21st centuries.
A sun cross, solar cross, or wheel cross is a solar symbol consisting of an equilateral cross inside a circle.
A gender symbol is a pictogram or glyph used to represent sex and gender, for example in biology and medicine, in genealogy, or in the sociological fields of gender politics, LGBT subculture and identity politics.
Miscellaneous Symbols is a Unicode block (U+2600–U+26FF) containing glyphs representing concepts from a variety of categories: astrological, astronomical, chess, dice, musical notation, political symbols, recycling, religious symbols, trigrams, warning signs, and weather, among others.
The National Emblem of Iran since the Iranian Revolution features four curves and a sword, surmounted by a shadda. It is very similar to the Sikh Khanda symbol. The emblem was designed by Hamid Nadimi, and was officially approved by Ayatollah Ruhollah Khomeini, the first supreme leader of Iran, on 9 May 1980.
Gemini (♊︎) is the third astrological sign in the zodiac. Under the tropical zodiac, the sun transits this sign between about May 21 to June 21. Gemini is represented by the twins, Castor and Pollux, known as the Dioscuri in Greek mythology. It is known as a positive, mutable sign.
An arrow is a graphical symbol, such as ← or →, or a pictogram, used to point or indicate direction. In its simplest form, an arrow is a triangle, chevron, or concave kite, usually affixed to a line segment or rectangle, and in more complex forms a representation of an actual arrow. The direction indicated by an arrow is the one along the length of the line or rectangle toward the single pointed end.
Historically, astrological and astronomical symbols have overlapped. Frequently used symbols include signs of the zodiac and classical planets. These originate from medieval Byzantine codices. Their current form is a product of the European Renaissance. Other symbols for astrological aspects are used in various astrological traditions.
A planet symbol or planetary symbol is a graphical symbol used in astrology and astronomy to represent a classical planet or one of the modern planets. The symbols were also used in alchemy to represent the metals associated with the planets, and in calendars for their associated days. Most of the symbols originated in Greco-Roman astronomy; their modern forms developed in the 16th century.
The Vergina Sun, also known as the Star of Vergina, Vergina Star or Argead Star, is a rayed solar symbol first appearing in ancient Greek art of the period between the 6th and 2nd centuries BC. The Vergina Sun proper has sixteen triangular rays, while comparable symbols of the same period variously have sixteen, twelve, eight or (rarely) six rays.
Unicode contains a number of characters that represent various cultural, political, and religious symbols. Most, but not all, of these symbols are in the Miscellaneous Symbols block.
Miscellaneous Symbols and Pictographs is a Unicode block containing meteorological and astronomical symbols, emoji characters largely for compatibility with Japanese telephone carriers' implementations of Shift JIS, and characters originally from the Wingdings and Webdings fonts found in Microsoft Windows.
A variety of symbols or iconographic conventions are used to represent Earth, whether in the sense of planet Earth, or the inhabited world, or as a classical element. A circle representing the round world, with the rivers of Garden of Eden separating the four corners of the world, or rotated 45° to suggest the four continents, remains a common pictographic convention to express the notion of "worldwide". The current astronomical symbol for the planet is a circle with an intersecting cross, . Although the International Astronomical Union (IAU) now discourages the use of planetary symbols, this is an exception, being used in abbreviations such as M🜨 for Earth mass.
