jorden?

Ja, fordi det er et navn, og navne staves jo med stort begyndelsesbogstav. På dansk skriver man også Jorden med stort J.

Ikke i følge min ordbog, hvilket er ret spøjst, da man staver de andre planetnavne med stort. En søgning på google viser da også, at mange vælger at stave det Earth. Så beklager, men jeg kan vist ikke give dig et entydigt svar.

...inden jeg siger noget forkert, vil jeg lige fortælle at det er forskelligt alt efter sætningen.

"Names of other planets and stars are proper nouns and begin with a capital letter: "The planet Mars can be seen tonight in the constellation Gemini, near the star Pollux."

The words sun, earth, and moon are proper nouns when the sentence uses them in an astronomical context, but not elsewhere: so "The Sun is a main sequence star, with a spectral class of G2"; but "It was a lovely day and the sun was warm". Note that these terms are only proper nouns when referring to a specific spectral body (our Sun, Earth and Moon): so "The Moon orbits the Earth"; but "Pluto's moon Charon"."

...taget fra Wikipedia.

In American English usage, the name can be capitalized or spelled in lowercase interchangeably, either when used absolutely or prefixed with "the" (i.e. Earth, the Earth, earth or the earth). Many deliberately spell the name of the planet with a capital, both as "Earth" or "the Earth". This is to distinguish it as a proper noun, distinct from the senses of the term as a count noun or verb (e.g. referring to soil, the ground, earthing in the electrical sense, etc.). Oxford Spelling recognizes the lowercase form as the most common, with the capitalized form as a variant of it. Another convention that is very common is to spell the name with a capital when occurring absolutely (e.g. Earth's atmosphere) and lowercase when preceded by "the" (e.g. the atmosphere of the earth). The term almost exclusively exists in lowercase when appearing in common phrases, even without "the" preceding it (e.g. it doesn't cost the earth; what on earth are you doing?).[2]
