Astronomy and cosmology

The shortest crossword solution for Billion-year period is 3 letters long and is called EON. The longest solution is four letters long and is called AEON.

One billion years may be called an eon in astronomy or geology. Previously in British English (but not in American English), the word "billion" referred exclusively to a million millions (1,000,000,000,000).

In official UK statistics the term is now used to denote 1 thousand million – 1,000,000,000. Historically, however, in the UK the term billion meant 1 million million – 1,000,000,000,000 - but in the United States the term was used to refer to 1 thousand million.

We believe the most likely solution is EON with 3 letters.

While billion may sounds like a made-up number like zillion — which just means a lot — it's a very real number, specifically 1,000,000,000. That's a pretty hard number to imagine, but one way to think of it is as a thousand millions. If you have a billion dollars, you're very rich: a billionaire.

A billion times a billion is one quintillion. This number is 10^18. A quintillion written in full is 1,000,000,000,000,000,000.

Similarly, one-million years is represented by “Ma,” meaning “mega annum.” One-billion years is abbreviated as “Ga” for “giga annum.” Sometimes geologists use “Kya” and “Mya” to characterize events that occurred, respectively, thousands or millions of years ago.
