Rules For Capitalization Questions Medium
No, the word 'planet' should not be capitalized unless it is used as part of a proper noun or at the beginning of a sentence. In general, common nouns like 'planet' are not capitalized unless they are part of a specific name or title. For example, in the sentence "Jupiter is a planet in our solar system," 'planet' is not capitalized because it is used as a common noun. However, in the sentence "I studied the planets in our solar system," 'planets' is not capitalized because it is still used as a common noun.
