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.
Many people have to stop and think if theyâre supposed to capitalize winter, spring, summer and fall (or autumn). Itâs the same problem people often have with whether or not to capitalize directions. As with the case of north, south, east and west, the answer is the same.
