You hear the word all the time, billion… but how big is one billion? It’s a **1** followed by nine zeros (1,000,000,000). That doesn’t seem very big, but it’s 1,000 MILLIONS. If you wanted to spend one billion dollars… You could spend a million dollars a year for 1,000 years OR you could spend a million dollars a MONTH for 83 years and 4 months. That’s a long time!!

I thought I would break ONE BILLION into chunks we can all understand, in units of seconds and miles (*time and distance*).

**How long is a BILLION seconds?**

- 1,000 seconds (1 thousand) = 16 minutes and 40 seconds
- 1,000,000 seconds (1 million) = 11 days, 13 hours, 46 minutes, 40 seconds
- 1,000,000,000 seconds (1 billion) = 31 years, 251 days, 13 hours, 34 minutes, 53 seconds

If you counted up to ONE BILLION, one number per second, it would take you almost 32 years without ever stopping (not even to sleep)!!

### How far is a BILLION miles?

The average distance between the Earth and the Moon is about 238,857 miles. If you traveled ONE BILLION miles you would be able to go to the moon and back to Earth about **2,093** times (it took Apollo 7, first landing on the moon, about **3 days and 4 hours** to go one-way to the moon). That is the same distance as traveling around our ENTIRE planet more than **41,158** times along the equator.

If you were on the Space Shuttle travelling at full speed (which can travel at speeds up to **17,500 MPH**; that is more than **23 times** the speed of a 9mm bullet leaving a gun), it would take you **6.52 years** to travel ONE BILLION miles.

I took the calculations from my memory. I will confirm my numbers (distance to the Moon and around the equator, speed of a bullet, etc.) and update this post. Don’t be jealous I know most those numbers off the top of my head!

I was off on the distance to the moon by about 13,000 miles, off of the time to travel to the moon by 4 hours and I re-wrote the bullet portion from a rifle to a 9mm bullet. I was pretty darn close!! I’m just saying…
