April 22 is Earth Day. Earth is capitalized in Earth Day because it's the name of a holiday, a proper noun. Earth isn't always capitalized though, and sometimes it seems to break the standard rules.
Other planet names are always capitalized (e.g.,Jupiter and Mars), but earth is often left lower case, especially when it comes after the: Protect the earth.
On the other hand, when people write about earth in an astronomical sense or in an article that includes other planets, earth is usually capitalized.
- We will move heaven and earth to find him.
- The spot on Jupiter is about as big as Earth.
Wow that is really interesting, i din't know that before. I will know for the future. This has helped me a lot. I wonder why the other planets are capitalized but earths not. I would have capitalized it before.
ReplyDeleteI agree with Kasym that it is very interesting. I too didn't know that before. Next time I'm writing about earth I will remember not to capitalize it. That's a good thing to ponder about.
