This is John Bachelor, conversation with my good friend Bob Zimmerman behind the black.

About 40 light years out, the discovery of an Earth-like planet, a little smaller than Earth, Bobbick,

0:12.0

introduces us to Gleeza 12b around a red dwarf

0:17.0

with a temperature on the surface in excess of 100 degrees Fahrenheit about 107 Bob says. What's important

0:26.2

here is that we're looking for planets that can sustain life like ours and this might be one.

0:33.0

Gleeza 12b, 40 light years out, reachable when and if we get close to 10% of the speed of light.

0:42.0

Big future. get close to 10% of the speed of light.

0:44.4

Big future.

0:46.1

Here's Bob.

0:47.1

This is a red dwarf star, a very small star.

0:50.0

They're the most stars you find in the universe.

0:54.0

It's 40 light years away.

0:55.4

They have found an exoplanet that orbits it every 12 plus days.

0:59.6

It's very close to the star, but it is a very dim star. So therefore that Earth and it's

1:05.2

Earth sized. It's a little bit smaller than the Earth. It's kind of like between

1:09.6

Venus and the Earth. It's considered to have a temperature about 107

1:14.4

degrees Fahrenheit, which means it's kind of like between the Earth and

1:18.0

Venus as well. If this planet has an atmosphere, it conceivably could be life sustaining it's probably

1:25.6

tightly locked with one side facing the star but once again it's a dim

1:29.3

star so there's possibilities here that this could be one of the first potentially habitable Earth-sized planets we have located John.

1:37.5

More data has to be gotten.
