...and it's not Nibiru (at least as far as I know)
The planet is one and a half times the size of Earth, so with the increased gravity to contend with the human race would struggle to move about. It doesn't mean to say however that mammals doesn't exist but they would require a bigger bone structure.
Yep, but that can evolve. Just need to work out how to travel in alternative ways to the conventional.
Although it would probably be Ok to communicate I wouldn't recommend visiting there. We all know what colonialism did to three quarters of the people of Planet Earth and I wouldn't want to repeat that. Also we are also protected by two million years of evolution from the worst nature can throw at us in terms of disease etc. C S Lewis once said that the vast interstellar distances are God's quarantine measures, preventing different civilisations and life forms from contaminating and wiping each other out as in H G Wells War of The Worlds.
There is no doubt that the biggest risk to planet Earth is mankind. We have build a legacy of raping our planet of it's natural wealth and poisoning it from within then kidding ourselves it's the individuals fault for putting the wrong thing in the bin and using carrier bags.
No, what interests me is that we are the 3rd planet from our sun with the right balance of oxygen and water to sustain life. Ever star is a sun, there has to be another planet in a similar potion.
If there is they properly won't need us to destroy it for them.
