What is Longer than a Millennium?

Have you ever wondered what comes after a millennium? A decade is 10 years, a century is 100 years, and a millennium is 1,000 years. But what’s longer than that?

The answer is an Eon. An Eon refers to a span of one billion years. Yes, you read that right – one billion years!

To put that into perspective, imagine the Earth’s history, which is approximately 4.5 billion years old. An Eon would be equivalent to about one-quarter of the Earth’s entire history.

But there are even larger units of time. After an Eon comes an Era, which is a period of several hundred million years. And then there’s the Supereon, which is the largest unit of time, comprising multiple Eons.

It’s mind-boggling to think about such massive scales of time. And yet, these units are essential in understanding and measuring the vastness of geological and astronomical events.

So, the next time someone asks you what’s longer than a millennium, you can confidently say it’s an Eon. And who knows, maybe one day we’ll have a new unit of time to describe even more enormous periods of time!
