Answer 2

Explanation:

Earth is referring specifically to the third planet from Sol. Planet is only a celestial body in orbit around a star. Sometimes people use "world" to reference planets AND Earth, but world is also used as a term specific to humanity, right now since humans are only on Earth it seems they overlap a lot.
