Planet Symbols of the Solar System

NASA maintains a page dedicated to the traditional planet symbols used to represent the worlds of our Solar System. It’s a small but useful resource that collects the familiar glyphs for Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto in one place.
You can explore the page here:
https://science.nasa.gov/resource/solar-system-symbols/
NASA also includes downloadable versions of the symbols, which makes the page particularly useful for teachers, students, and anyone creating educational materials or presentations about the Solar System.

At the top of the page, NASA places a short note explaining that the International Astronomical Union discourages the use of these symbols in formal scientific publications. In modern astronomical writing, standard text notation is preferred in order to keep research papers consistent and unambiguous.

That clarification reflects the conventions of scientific publishing today. At the same time, the symbols themselves remain widely recognizable because they come from a much older tradition of sky observation.

For most of human history, the study of the heavens was not divided the way it is today. What we now call astronomy and astrology developed side by side as observers tracked planetary motion and recorded the cycles of the sky. The symbols for the planets became a convenient shorthand within that shared language.

Over time the disciplines separated, but the planet symbols remained. They continue to appear in classrooms, books, and cultural references whenever the planets are represented visually.

NASA’s page presents these solar system symbols in a straightforward way — simply as a reference for the glyphs associated with each planet.

For educators especially, it’s a practical resource. The downloadable symbols can easily be used in lesson materials, worksheets, presentations, or student projects involving the Solar System.

Celestial Note

Sometimes a small page like this quietly preserves a piece of our long relationship with the sky — where the language of observation and the language of symbols once developed together.

Sources & Foundations

If you’re curious to see the original source, NASA maintains a page dedicated to the traditional Solar System symbols used to represent the planets. The resource presents the familiar glyphs in a clean reference format and includes downloadable graphics that can be used in classrooms, presentations, or personal projects. From there, visitors can easily explore other astronomy resources across NASA’s site — from planetary science pages to images, missions, and educational materials that bring the structure of our Solar System into clearer view.
