This page lists all the various symbols in the Astronomical Symbols category.
Astronomical symbols are symbols used to represent various celestial objects, theoretical constructs and observational events in astronomy. The earliest forms of these symbols appear in Greek papyri of late antiquity. The Byzantine codices in which the Greek papyri were preserved continued and extended the inventory of astronomical symbols. New symbols were further invented to represent many just-discovered planets and minor planets discovered in the 18th-20th centuries.

37 Fides (pron.: /ˈfaɪdiːz/ FY-deez) is a large main-belt asteroid. It was discovered by German astronomer Karl Theodor Robert Luther on October 5, 1855, and named after Fides, the Roman goddess of loyalty. Fides was the last of the main-belt asteroids to be assigned an iconic symbol.
Ceres, minor-planet designation 1 Ceres, is the only dwarf planet in the inner Solar System, and the largest asteroid. It is a rock–ice body 950 km (590 mi) in diameter, and the smallest identified dwarf planet. It contains about one third of the mass of the asteroid belt. Discovered on 1 January 1801 by Giuseppe Piazzi, it was the first asteroid to be identified, though it was classified as a planet at the time. It is named after Ceres, the Roman goddess of growing plants, the harvest, and motherly love.
The Moon is the only natural satellite of the Earth, and the fifth largest satellite in the Solar System. It is the largest natural satellite of a planet in the Solar System relative to the size of its primary, having 27% the diameter and 60% the density of Earth, resulting in 1⁄81 its mass. The Moon is the second densest satellite after Io, a satellite of Jupiter.
A pentacle (or pantacle in Thelema) is an amulet used in magical evocation, generally made of parchment, paper or metal (although it can be of other materials), on which the symbol of a spirit or energy being evoked is drawn. It is often worn around the neck, or placed within the triangle of evocation. Protective symbols may also be included (sometimes on the reverse), a common one being the five-point form of the Seal of Solomon, called a pentacle of Solomon or pentangle of Solomon. Many varieties of pentacle can be found in the grimoires of Solomonic magic; they are also used in some neopagan magical traditions, such as Wicca, alongside other magical tools.
The Star of Venus also called the Star of Ishtar is an ancient symbol originating in Iraq used as early as 2000 BCE that represents the planet Venus, historically to represent the Babylonian and Assyrian Goddess Ishtar that are connected with Venus, as well as being historically used by Phoenician culture to represent Venus and the goddess Astarte (a counterpart of Ishtar)
