Planet and astronomy symbols are the traditional glyphs for celestial bodies: โ the Sun, โฝ and โพ the crescent Moon, โฟ Mercury, โ Venus, โ or โ Earth, โ Mars, โ Jupiter, โ Saturn, โ Uranus, โ Neptune and โ Pluto. Most derive from classical and medieval alchemical and astrological notation, and Unicode places them in the Miscellaneous Symbols block. Astronomers and astrologers use them as shorthand in charts, ephemerides and natal wheels; the Venus (โ) and Mars (โ) glyphs doubled as the standard female and male symbols. Paste them into astrology posts, horoscope captions, science and astronomy notes, worldbuilding and tabletop games, star-chart diagrams, and aesthetic bios or usernames. Their old, celestial look makes them popular for cosmic-themed profiles, tattoos and jewelry engraving too.
Planet & Astronomy Symbols to Copy
Origins and What Each Glyph Means
These symbols come from Greek and Roman planetary lore, refined through medieval astrology and alchemy. โ is a circle with a central dot for the Sun; โฝ is the waxing Moon. The planets often encode a deity's attribute: โ shows Mars's shield and spear, โ Venus's hand mirror, โฟ Mercury's caduceus and winged cap, โ a stylized Jupiter monogram, and โ Saturn's sickle. Uranus (โ ), Neptune (โ) and Pluto (โ) are newer, designed after their discoveries; Pluto's glyph combines the letters P and L. Unicode stores them in Miscellaneous Symbols, so they render as ordinary text characters.
Charts, Captions and Cosmic Aesthetics
Astrologers use these glyphs throughout natal charts and horoscopes to mark where each planet falls, and astronomy references use โ and โ as compact stand-ins for the Sun and Earth in formulas and tables. Writers and tabletop gamers borrow them for sci-fi settings, faction sigils and star maps. On social media they show up in bios, usernames and captions for a celestial, mystical vibe, and in playlist and channel names themed around space. Jewelers and tattoo artists engrave a birth planet or a Sun-and-Moon pairing, and educators drop them into worksheets and slides about the solar system.
Frequently Asked Questions
Why are the Venus and Mars symbols also used for gender?โผ
Biologist Carl Linnaeus adopted the astrological glyphs for Venus (โ) and Mars (โ) in the 1750s to mark female and male in his botanical work, and the convention stuck. So the same characters serve double duty: planetary symbols in astronomy and astrology, and the familiar female and male signs in biology, forms and everyday design.
Is there a symbol for Earth?โผ
Yes, two common ones. โ is a cross atop a circle, and โ is a circle with a cross through it representing a globe with meridians. Both appear in Unicode and are used interchangeably for Earth in charts and science writing. Astronomers frequently use โ as a subscript to denote Earth-relative quantities like mass or radius.
Do these symbols display the same on every device?โผ
The core planetary glyphs are widely supported and render as text on modern phones, browsers and operating systems. A few, like some Moon variants, may show a slightly different style depending on the font, but they should not appear as empty boxes on current devices. Older systems occasionally lack the newer Uranus, Neptune or Pluto glyphs.
