1 Mars â Sometimes called the red planet and the brother of Earth. 2  Mars is the closest planet to the Earth. 3  Jupiter â The largest planet in the Solar System. 4  Saturn â Sixth planet from the Sun.
1 When talking about a general direction, the word is often not capitalised, example: the north side of the house. 2  Place names are capitalised: East Sussex, West Virginia, South Africa.  In other cases, adjectives and nouns normally begin with small letters: Go south for three miles, then go east for another three miles.
Just as important as knowing when to capitalize is knowing when not to. Below, I set forth a few instances where capital letters are commonly used when they should not be. Please review this advice carefully, in that we all have made such capitalization errors.o not capitalize the words north, south, east, and west when they refer to directions, in that their meaning becomes generalized rather than site-specific. In general, do not capitalize commonly used words that have come to have specialized meaning, even though their origins are in words that are capitalized.
