What if the Planets had their Own Flags?

This is the planetary flag of Mercury. The orange and red stripes represent its proximity and affinity to the Sun. In the upper middle portion, the Sun can be seen, which is intercepted by the symbol of Mercury in grey colour located in the centre. See this flag waving here!

This is the international... sorry, the interplanetary flag of Mercury. The yellow arc in the left-hand side is the Sun. Mercury can be seen in front of the Sun. One-half of the planet is brightly lit signifying daytime, while the other half is dim signifying night. In the top right corner, the symbol of Mercury can be seen in orange. The dark blue field marks the space. See this flag waving here!

The flag of Venus is very unique, given that it is very colourful. The gold stripe at the bottom represents the hellish soil of the planet, followed by two stripes of brown and cream representing the dense cloud cover, and finally the blue stripe represents the sky and the human civilisation present there. In the centre is the Star of Ishtar (or the Star of Inanna), a Sumerian symbol for the planet. It is coloured red to represent its proximity to the Sun. See this flag waving here!

The interplanetary flag of Venus is very simple. On a dark blue field representing the space, the silhouette of the planet could be seen. It is surrounded by its thick atmosphere. In the top right corner, the symbol of Venus is present in brown. See this flag waving here!

The flag of Mars is inspired by this flag by Pascal Lee. The tricolour represent the transformation of the Red Planet from a lifeless planet to one deeming with life. The sky blue boundary depict the human population located there and its affinity to the Earth. In the top right corner, within the dark blue stripe, the symbol of Mars can be seen. See this flag waving here!

The interplanetary flag of Mars is a simple flag. It features the silhouette of the Red Planet in the centre, accompanied by its two moons – Phobos and Deimos on its either sides. In the top right corner, the symbol of planet is present as usual. See this flag waving here!

The flag of Jupiter is clearly my favourite. Just look at it! In the left-hand side, you can see a silhouette of Jupiter, with the Great Red Spot taking up a prominent spot. In the right side, the four largest moons of the planet are depicted by white four-pointed stars. I decided to omit the symbol for Jupiter because it is already too recognisable. Actually, I found this design on Reddit. So, thanks to that user for coming up with such a creative design! See this flag waving here!

The Ring Planet's flag also features a silhouette of the planet. I could not draw the rings properly, it was very hard! The small discs above the planets are three of its most famous moons – Enceladus, Titan and Rhea respectively. In the top right corner, the symbol of Saturn can be seen. This flag was slightly altered on the suggestion of user Puvlin. See this flag waving here!

This is also a great design. I think I'm being narcissistic, because I designed them all! Anyway, this flag incorporates the colour blue in it prominently because Uranus is made mostly of water, hydrogen and methane. In the right side, a silhouette of the planet is visible. One of the most prominent features of this flag are the rings, which have been merged into one single ring for the sake of simplicity. In the left side, the symbol of Uranus can be seen. See this flag waving here!

The Neptunian flag is also prominently blue in colour like that of its twin. However, the shade of blue is darker. It features wave-like stripes representing high speed winds known to flow on the planet. In the centre is a stylised version of the symbol of Neptune, the Trident of Poseidon.

Let's not leave the satellites! Here is the flag of our Moon:

The flag of the Moon is probably my favourite. It has a simple design. The dark blue and silver go hand in hand. In the centre is a crescent. I included the crescent because a circle would have been too obvious. In the canton is the symbol of the Earth, symbolising the close relationship between Terra and Luna. See this flag waving here!

Europa is the smallest of the four Galilean moons of Jupiter. It is widely believed that underneath the icy surface of the moon, there exists a vast ocean, which could potentially support life. The flag is an obvious visualisation of this belief. In the canton, a four pointed star represents Jupiter and in the top right corner, the symbol of Jupiter is present. See this flag waving here!

Titan is the only body within the solar system other than Earth where surface liquid has been found. It is widely believed to host some form of life. The flag of Titan features several stripes – the bottom yellowish stripe represents its soil, the blue stripe represents the water and the white stripe represents ice. In the canton, a yellow diamond sign which includes a silhouette of Saturn, along with its symbol, can be seen. See this flag waving here!

Pluto is NOT a planet, but it shouldn't be omitted altogether. I drew flags for the moons, then why should I leave our old friend Pluto? Here is the flag of Pluto:

Looks cute, eh? It depicts the Pluto-Charon binary system. Charon is the largest moon of Pluto (Pluto has 5 moons!). The heart shape is a region on the dwarf planet now known as Tombaugh Regio. See this flag waving here!

It seems we have covered everything. No! We missed the Solar System! Here is the flag for the Solar System:

The flag of Solar System has a very straightforward design. Kind of like how the kids draw the Solar System. With this abstract idea, I tried to visualise all of the planets and some of the moons (sorry Pluto!) into a single flag. In the centre is the massive Sun. This flag is clearly not drawn to scale. See this flag waving here!

Since the planets are colonised, we need something like the United Nations. A supranational... sorry, an interplanetary association for all the planets. Let's call it the United Planets Association for the time being. This idea was suggested by user JWatson24.

On a blue field symbolising the space, the symbol of sun is inscribed in gold in the centre. Two olive branches represent peace. In the left-hand side, two thick stripes portray the inner and outer planets. In between them, a thinner stripe depicts the asteroid belt, an often forgotten yet an important part of the Solar System. This flag can also be used to represent all of the Solar System. See this flag waving here!

OK! So, we have covered everything... except our own planet, Earth! Now, there exists a lot of proposals for the flag of the Earth. Here are some of them:

They are all good designs, however, I feel that they do not represent all of the planet. And going by theme of this blog, I have to make flags for the Earth too. A democratic voting was conducted between 6th to 13th of October to choose the flags of Earth. Check the winning flags below!

This flag is called the Unity Flag. It is a modification of the International Flag of Earth designed by Pernefeldt. With 13 votes, this flag is unofficially declared the planetary flag of the Earth. On a blue field, seven rings are linked to each other creating a flower. It represents how everything on Earth is connected either directly or indirectly. The inner boundary is of different colours and meet each other in the corners, representing the cultural, geographical and biological diversity of the planet. The outer white boundary symbolises peace and harmony.

The user plattitude gave some valid points regarding the design being somewhat complex and unsymmetrical. However, having received the largest number of votes, I felt changing it would be deceitful to those who have voted for it. So, the flag stays as it was in the first iteration of the blog. See this flag waving here!

Receiving 8 votes, I'm delighted to announce this flag as the interplanetary flag of the Earth. It is called the Terra and Luna flag. On a dark blue field marking the space, the Earth can be seen. I drew out the Pangaea supercontinent, so that none of the today's continents feel left out. In the right side, the moon can be seen. This flag should be used in interplanetary missions and voyages between the Earth and other planets. I'm pretty fond of this design. See this flag waving here!

I decided to call this flag the Four Domains of the World Flag. The symbol of Earth is drawn on an indigo field. The four quadrants mark the geographical diversity of the planet and also the four elements of nature. The blue quadrant represents the water; the green quadrant represents the forests, the trees and the soil; the yellow quadrant represents the deserts and fire; and the white quadrant represents the mountains, the polar regions and also the air. Unfortunately, this flag received only 6 votes. I don't want to disregard this flag completely. Hence, this flag can be used unofficially to represent our planet. See this flag waving here!
