【Earthly】 , 【terrestrial】 , 【earthy】 , 【mundane】 , 【worldly】 , 【sublunary】 are comparable when they mean of, belonging to, or characteristic of the earth.

【Earthly】 is used chiefly in opposition to heavenly.

【Terrestrial】 is sometimes used in place of 【earthly】  as a more sonorous term; frequently, however, it implies an opposition to celestial rather than to heavenly or it may imply a distinction of earth from the other planets or more specifically in astronomy, a distinction of certain planets assumed to be like the earth from others assumed to be unlike the earth.

【Terrestrial】 in some use suggests land as a habitat, rather than water or trees.

【Earthy】 , in the historical development of its senses, has stressed a connection with the earth as soil rather than the earth as the abode of men.

Even when it comes close to 【earthly】 in its meaning, it carries a stronger implication of grossness of substance or of material interests than 【earthly】 and is opposed more to spiritual than to heavenly.

【Mundane】 and 【worldly】 both imply a relationship to the world thought of as the affairs, concerns, and activities of human beings especially as they are concentrated on practical ends or on immediate pleasures. 【Mundane】  specifically suggests an opposition to what is eternal and stresses transitoriness or impermanence.

【Worldly】 , which is applied chiefly to persons and their interests, specifically implies indifference to things of the spirit and concentration on whatever satisfies one’s love of success, one’s desire for pleasure, or one’s self-esteem.

【Sublunary】 is a distinctly literary or poetic term variously interchangeable with  【earthly】 , 【mundane】 , and 【terrestrial】 .
