Planetary Civilization Flags
An Open Source Project for Unification of Our Civilization.
We must unite
or we will perish
as a species
Together as humans, we’re facing climate change, wars, pollution, economic inequality, hate crimes, violations of civil rights, government distrust, natural resource depletion and more horrendous issues that need to be resolved in order for us to survive.
The project aims to unify our cultural differences, establish common ground, and envisage a clear path into our future.
“Orbiting Earth in the spaceship, I saw how beautiful our planet is. People, let us preserve and increase this beauty, not destroy it!”
—Yuri Gargarin
“Every one of us is, in the cosmic perspective, precious. If a human disagrees with you, let him live. In a hundred billion galaxies, you will not find another."
— Carl Sagan
What is a planetary civilization?
In 1964, Soviet astronomer Nikolai Kardashev defined three levels of civilizations, based on the order of magnitude of power available to them.
Type I: 1016
Planetary civilization
Can use and store the total energy which reaches its planet from its parent star.
Type II: 1026
Stellar civilization
Can harness the total energy of its planet's parent star.
Type III: 1036
Galactic civilization
Can control energy on the scale of its entire host galaxy.
“These civilizations can effectively control the entire resources of their planet; they can predict weather patterns and earthquakes very accurately, and even control them using artificially induced greenhouse effects or space-based lasers. A Type 1 Civilization could conceivably halt an ice-age."
—Dr. Michio Kaku

The second planet from the Sun and our closest planetary neighbor. Similar in structure and size to Earth, Venus spins slowly in the opposite direction from most planets. Its thick atmosphere traps heat in a runaway greenhouse effect, making it the hottest planet in our solar system with surface temperatures hot enough to melt lead. Glimpses below the clouds reveal volcanoes and deformed mountains.

Venus is named for the ancient Roman goddess of love and beauty, who was known as Aphrodite to the Ancient Greeks.



Our home planet is the third planet from the Sun, and the only place we know of so far that’s inhabited by living things. While Earth is only the fifth largest planet in the solar system, it is the only world in our solar system with liquid water on the surface. Just slightly larger than nearby Venus, Earth is the biggest of the four planets closest to the Sun, all of which are made of rock and metal.

The name Earth is at least 1,000 years old. All of the planets, except for Earth, were named after Greek and Roman gods and goddesses. However, the name Earth is a Germanic word, which simply means “the ground.”



The fourth planet from the Sun—is a dusty, cold, desert world with a very thin atmosphere. This dynamic planet has seasons, polar ice caps, extinct volcanoes, canyons and weather. Mars is one of the most explored bodies in our solar system, and it’s the only planet where we’ve sent rovers to roam the alien landscape. NASA missions have found lots of evidence that Mars was much wetter and warmer, with a thicker atmosphere, billions of years ago.

Mars was named by the Romans for their god of war because of its reddish color was reminiscent of blood. The Egyptians called it “Her Desher,” meaning “the red one.” Even today, it is frequently called the “Red Planet” because iron minerals in the Martian dirt oxidize, or rust, causing the surface to look red.



The fifth planet from our Sun and is, by far, the largest planet in the solar system - more than twice as massive as all the other planets combined. Jupiter’s stripes and swirls are actually cold, windy clouds of ammonia and water, floating in an atmosphere of hydrogen and helium. Jupiter’s iconic Great Red Spot is a giant storm bigger than Earth that has raged for hundreds of years.

Jupiter is named for the king of ancient Roman gods.



The sixth planet from the Sun and the second largest planet in our solar system. Adorned with a dazzling system of icy rings, Saturn is unique among the planets. It is not the only planet to have rings, but none are more spectacular or as complex as Saturn’s. Like fellow gas giant Jupiter, Saturn is a massive ball made mostly of hydrogen and helium.

The farthest planet from discovered by the unaided human eye, Saturn has been known since ancient times. The planet is named for the Roman god of agriculture and wealth, who was also the father of Jupiter.



The seventh planet from the Sun with the third largest diameter in our solar system—is very cold and windy. The giant planet is surrounded by faint rings and more than two dozen small moons as it rotates at a nearly 90-degree angle from the plane of its orbit. This unique tilt makes Uranus appear to spin on its side.

The first planet found with the aid of a telescope, Uranus was discovered in 1781 by astronomer William Herschel, although he originally thought it was either a comet or a star. Herschel tried unsuccessfully to name his discovery Georgium Sidus after his patron, English king George III. Instead, the planet was eventually named for Uranus, the Greek god of the sky, who was also the father of Kronos (or Saturn).



The eighth and most distant major planet orbiting our Sun—is dark, cold and whipped by supersonic winds. More than 30 times as far from the Sun as Earth, Neptune is not visible to the naked eye. In 2011, Neptune completed its first 165-year orbit since its discovery.

Neptune was the first planet located through mathematical calculations. Using predictions made by Urbain Le Verrier, Johann Galle discovered the planet in 1846. The planet is named after the Roman god of the sea, as suggested by Le Verrier.



A yellow dwarf star, a hot ball of glowing gases at the heart of our solar system. Its gravity holds the solar system together, keeping everything - from the biggest planets to the smallest particles of debris - in its orbit. The connection and interactions between the Sun and Earth drive the seasons, ocean currents, weather, climate, radiation belts and auroras. Though it is special to us, there are billions of stars like our Sun scattered across the Milky Way galaxy.

The Sun has many names in many cultures. The Latin word for Sun is “sol,” which is the main adjective for all things Sun-related: solar.

Some individuals and organizations have promoted designs for a flag representing the planet Earth, though none have been officially recognized as such by any governmental body. Widely recognized flags associated with Earth include the flag of the United Nations.
The authors of Planetary civilization flags found out there were some attempts already put to practice only after they designed the Earth flag. The logic of the predecessors was the same - Earth as a planet in our solar system. The authors even found almost exact design being made in 1970 by James W. Cadle (USA).

Responisble towards people and the planet
Today, flags are mostly made of printed polyester fabric since its production is cheap and fast. Such a method is unsustainable due to the production of synthetic materials and the fact that it becomes plastic waste at the end of its lifetime. At the same time, printed flags neither have the quality nor the aesthetics of traditional, sewn flags. A flag that symbolizes responsibility, justice, solidarity, and connectedness, and promotes efficient use of energy resources, should be made according to these principles. Therefore, capitalist ways of production based on exploiting natural resources and workforce are inappropriate.
This project aims to change the way we think and act. The designs for Planetary Flags are open-source, meaning anyone can use them to make their own flags and spread the message about the globally connected civilization. We make our flags collaborating with an ethical small-scale production facility, using waste fabric, preserving traditional crafts and local business. We believe such ways of organizing are crucial to establish resilient social structures and cope with the uncertain times to come. Please consider this yourself when using our open-source design.
We’ll let you know when other flags are available
