So just how far is 600 light years?

Let's revisit some number sense:

We know that light travels at the approximate speed of 300,000 kilometers per second.

There are 60 seconds in a minute:
300,000 x 60 = 18,000,000km in a minute

There are 60 minutes in an hour:
18,000,000 x 60 = 1,080,000,000km in an hour

There are 24 hours in a day:
1,080,000,000 x 24 = 25,920,000,000km in a day

There are 365 days in a year:
25,920,000,000km x 365 = 9,460,800,000,000km in a year

That number times 600 years:
9,460,800,000,000 x 600 = 5,676,480,000,000,000km

Basically, Kepler-22b is 5,676,480,000,000km away from Earth -- meaning that travelling at the speed of light, at 300,000km per SECOND, it would take you 600 years to traverse 5,676,480,000,000km across space!

Doesn't sound THAT far? To put that into perspective, consider this: a beam of light travels 7.5 times around Earth in just 1 second!

Astronomers have confirmed the existence of an Earth-like planet in the "habitable zone" around a star not unlike our own.

Check out this really cool link from the BBC. 

The world's population is expected to hit seven billion in the next few weeks. After growing very slowly for most of human history, the number of people on Earth has more than doubled in the last 50 years. Where do you fit into this story of human life?
