what is the official name for planet earth, when and by whom was it decided?

Answer 1

Earth

Answer 2

The story behind the names of the planets was written long ago by early stargazers -- the first astronomers to focus attention on the sun, the moon, and the visible planets Mercury, Venus, Mars, Jupiter, and Saturn. They believed that each of these celestial bodies influenced a particular day of the week. Diverse cultures ascribed the names of their gods to individual planets (with the notable exception of Earth).
The Romans matched planetary attributes with particular deities and named the known planets accordingly. Tiny Mercury was named after the fleet-footed messenger to the gods, probably because it moves so quickly across the sky; Venus, the brightest planet visible to the unaided eye, was named for the goddess of love and beauty. Jupiter, more than twice as massive as all the other planets combined, earned the name of the superior god.

These Roman names were adapted by early European astronomers and have persisted, long after the ancient geocentric model of our solar system was proven wrong.

Uranus was the first planet discovered in modern times. In 1781, British astronomer William Herschel named it "the Georgium Sidus" (The Georgian Planet) after the notorious King George III. However, the German astronomer Johann Bode proposed "Uranus" to conform with the existing planetary names. These days, the hard-working scientists who find the planets get to choose their names.

Although English is recognized as the international language of professional astronomy and planetary nomenclature, different languages have their own planetary names that are commonly used in everyday conversation.

Who would have the authority to make that decision? Us? The French? The UN? Science fiction writers often call it Terra, but that isn't a rule.

"Lexicography

Terms that refer to the Earth can use the Latin root terra-, such as the word terrestrial. There is also the alternative Latin root tellur-, as used in words such as telluric, tellurian, tellurion and Tellurium. Both terms derive from the Roman goddess Terra Mater, who was also called by the presumably more ancient name Tellūs Mater. Scientific terms such as geography, geocentric and geothermal use the Greek prefix geo-, derived from Terra Mater's Greek counterpart Gaia.

The English word "earth" has cognates in many modern and ancient languages. Examples in modern tongues include aarde in Dutch and Erde in German. The root also has cognates in extinct languages such as ertha in Old Saxon and ert (meaning "ground") in Middle Irish, derived from the Old English eorðe. All of these words are derived from the Proto-Indo-European base *er-. Given metathesis, we can find cognates of "earth" between terra and the modern Romance languages, for instance tierra in Spanish or terra in Portuguese.

Several Semitic languages have words for "earth" similar to those in Indo-European languages, although evidence of a link is not overwhelming. Arabic has aard; Akkadian, irtsitu; Aramaic, araa; Phoenician, erets (which appears in the Mesha Stele); and Hebrew, ארץ (arets, or erets when followed by a noun modifier)."
