Distant "fluffy" planet discovered

Thursday, astronomers discovered a new planet so "puffy" that it would float in water. This new planet named HAT-P-1, is the largest and least dense planet found outside our solar system. 450 light-years from Earth, HAT-P-1 orbits a star in the constellation Lacerta. This planet is a gas giant, composed of hydrogen and helium. Robert Noyes, a research astrophysicist from the Smithsonian Astrophysical Observatory, claims HAT-P-1 would "float if placed in a cosmic glass of water." HAT-P-1 orbits its parent star at one-twentieth the distance that seperates Earth and the sun, taking only 4.5 days to orbit, versus our 365 days! HAT-P-1 was discovered by a network of telescopes in Hawaii and Arizona. It is too distant to be seen with the naked eye, but visible with binoculars.

10 x 365 =3650
+ 240 = number of days Kenny has been alive = 3890 days.

On the new planet 3890 days = how many years?

3890/9 = 432 x 2 = 864 years old on the fluffy planet!
