That planet is 1.5x bigger than earth, meaning 1.5x the gravity. We'd have a tough time walking around there. 13 day year would make me dizzy.
A light year is about 10 million million km. Closest star to our own is Alpha Centauri which is 4.3 light years away or 43 million million km away.
Mars is anywhere from 56,000,000 km to 399,000,000 depending on our orbits.
If you were talking to someone on mars I think the delay would be somewhere around 27 minutes (again, depending on orbit).
Talking to someone on this new planet, the delay would be 20 years. I guess that's an easier way to put it into perspective.
Anyone watching that Mars Rising program on Discovery recently? Their basically saying a round trip time of 1,000 days to mars including 18 months on the planet. So you're basically looking at 500 days travel time there and back with earth technology. Probably somewhere in the range of 100,000km/h.
Just for somparison sake, the ISS in Low Earth Orbit goes along at around 30,000km/h.
