Habitability of a Hypothetical of the Circumbinary Kepler 1647b…

or

Is Pandora around Kepler1647b ?

This is me:

Kepler 1647b

Pandora A Distance: 2.7 AU Star A

Star B

Star B

Kepler 1647b

The planet is so large that it could have A is a The is made moons like Pandora - Avatar’s moon - planet that orbits two (a of sun like stars.The age binary star). Kepler 1647b is a of the system is 4.4 Gyr size planet around a binary star.

In our Solar System But Pandora is habitable, right? Too Cold It could be Just right How long habitable for could it be Kepler 1647b 5.8 Gyr, a Ceres Keeps habitable a long time now! Kepler 1647b habitable? considerable Star A Distance to the star (AU) Just right Too hot time. The age Star B of the Earth is Mars 4.6 Gyr.

Too Cold Too hot Earth

Time (Gyr) The star dies Kepler 1647b is inside the Birth of the star

Habitable Zone The properties of the star changes in time

And two stars is not too much?

The planet could Wait a minute… have several moons Dangerous for life What about the In the Solar system protected by his Magnetic field? 15 RJ magnetic field. The Flux in X-ray and UV of the stars could be completely shielded Kepler 1647b now! if they are located less than 15 radii of Time (Gyr) Jupiter from the sur- face of the planet.

The and his moon re- ceive less flux in X and UV than Earth at his current age. X-ray and extreme ultraviolet radiation (UV) flux are like the levels on Mars. In conclusion: If Kepler 1647b has a moon it could be plenty of life!
