.Amamamama!! flip flop!! Would be nice ni haina? to have a vacation outside the Solar System. How many "light days" of vacation we need to get to enjoy the fullest re kya. Whenever I read about astronomy, I feel like our life is too short. BathroomCoffee, thanx for sharing this. Can anyone explain this to me please? "...If it is rocky like Earth, which is what the prevailing theory proposes, it has a diameter about 11/2 times bigger than our planet. If it is an iceball, as Mayor suggests, it would be even bigger..." How can it be bigger if it made of iceball? Good night :-)
