A Flag for Earth
The North American Astrophysical Observatory (NAAPO) has administered a flag to represent the earth.
Earth Flag
The Flag of Earth symbolizes the Earth (the center blue disk), the Sun (the yellow disk on the left), and the Moon (the white disk on the right). The Earth and its most important celestial neighbors – the Sun and Moon – are overlaid on a backdrop of the darkness of space.
