New Earth?


The Guardian reported this past Spring that astronomers at the European Southern Observatory have discovered another planet that could be very Earth-like in its development and could, in fact, contain an oxygen atmosphere and enough water to sustain life as we know it. The article is here.

The planet is called "Gliese 581c" and it circles a red dwarf star about 20 light years away. It's quite a bit closer to that star than we are to our own sun, but because Gliese 581 burns so much cooler than our sun, it all evens out. It's about one-and-a-half times as big as our home here on Earth. The temperature ranges from about 30 to 110 degrees Fahrenheit (or 0 to 40 Celsius).

The thing I found most interesting is that its orbit lasts only 13 days. That's the equivalent of a year in just under two weeks. I'm trying to wrap my head around that.

Using what measurements we know, you'd have to get paid about twice a day. Vacations and holidays would be measured in hours. You'd just be getting over one New Year's Eve party when, whoops, here comes another one!

"Hey, how old are you?"
"About a hundred and twenty minutes!"

At 20 light years and our current methods of space travel, it would only take about 375,000 years to reach Gliese 581c.

Hmmm. Better get started.
