“Scientists estimate the temperature of Gliese 887c to be around 70oC.”

Not sure if that is a typo meaning 70C or 700C. Either way, hot!
And if they are so close in, would they be tidally locked?

I get that “super earth” is a name they came up with so people get an idea of what they are talking about, but I do not like the term.

“Large terrestrial planet” seems more accurate.
Using the word Earth in it leads to the assumption of a green living healthy water world.

For all we know, they could just be giant rocks, or micro gas planets (/sarc on that last one).

Wow! Only 65 trillion miles away!!! Maybe we can build a ship for the anarchist left so they can go create their utopia there?
