Pondering Kepler-22

I was just reading an article to my cousins about the discovery of Kepler-22, the newest discovered Earth-like planet. Some 600 light years away, a planet almost two and a half times the size of Earth is orbiting a star much like our sun. Talking about it with them brought some interesting facts to light.

1. If we had a space craft that could travel at the speed of light, the astronauts on the mission would have to give birth to at least 20 generations of offspring in order to complete the journey to Kepler-22. This is assuming that people give birth roughly every 30 years from the start of the mission. So think about generations of people born at the speed of light, never knowing still life on the ground.

2. I believe that our lives on Earth are heavily influenced by the planets in our solar system, especially the moon. The tides, when things grow and reproduce, our menstrual cycles, are all influenced by the moon. Imagine what effect not having a moon, or having three moons, would have on us if we lived on a different planet.

3. Kepler-22 is 2.4 times the size of Earth. That means that if Kepler rotates at the same speed as Earth, our days would be nearly 60 hours long.

That made me wonder other things, like how many 60 hour days it takes Kepler to rotate its sun, and how that would effect our concept of time and our lifespan. Would it suddenly go from 80 years to 40? How long would our seasons be? Would life seem shorter if we knew we had half as many winters or would time seem to go by slower if our seasons were 2.4x, or 4x or 6x longer?

Just some interesting things to ponder.
