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. Listed below are some of the most commonly recognized flags of Earth:

United Nations flag[edit]

Adopted in 1946, the flag of the United Nations has been used to indicate world unity, although it technically only represents the United Nations itself. It has a geographical representation of the planet, and its high visibility usage makes it a well-known contender for representing Earth. During the planning for NASA's Moon landings of the 1960s, it was suggested that a UN flag be used in place of the flag of the US.[1]

Other private proposals[edit]

James W. Cadle's "Flag of Earth"[edit]

Flag of Earth by James Cadle

In 1970 by James W. Cadle, a farmer from Homer, Illinois, created his own version of a flag of Earth.[2] Cadle's flag consists of a blue circle representing Earth in the center of the flag, a segment of a large yellow circle representing the Sun and a small white circle for the Moon, all on a black background. It is particularly popular among SETI researchers and is used by the SETI League.[3] The flag flies at the Ohio State University Radio Observatory and was lowered to half mast when Carl Sagan died.[4] Flag of Earth Co. International, which sold the flag, was also founded by Cadle. The Flag of Earth became public domain in 2003.[5]

Paul Carroll's "World Flag"[edit]
