Emphasis of Terra in the lead   The first paragraph of the lead was changed to the following  Earth Latin Terra  is the third planet from the Sun and is the largest of the terrestrial planets in the Solar System in both diameter and mass Home to a myriad of species including the dominant animal humans it is also referred to as the Earth Planet Earth Gaia the World and its official scientific name is the Latin Terra after the Roman goddess Terra it is the only planet in the Solar system which is known commonly by an english translation of its actual Latin name  However the assertions about an official IAU name are unsourced so it needs a valid citation Otherwise Im not sure I see a valid need to place such an emphasis on the latin name of the planet
