When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun.
It is a common misconception that “Terra” is the internationally-recognized scientific name of the planet, but in reality Earth does not have an official international name.
The standard English name of the planet, including in science, is “Earth”.
Earth is the third planet from the Sun at a distance of about 93 million miles (150 million km).
