The copy you have in the above post does not match the copy of the article?
But from the article if you follow the link:
“A mini-planet orbiting in the frigid outer reaches of the solar system...”
which prompted me to remember years ago I read that the temperature in outer space is everywhere an even 70 Degrees! I’m not kidding! I DID read that!
So I looked up ‘what is the temperature in outer space’ just to see what it was because the article said ‘in the frigid outer reaches of the solar system’ and THIS is what I found:
“The temperature in outer space is generally 2.73 Kelvin (-270.42 Celsius, -454.75 Fahrenheit)”.
A bit colder than 70 degrees.
Did they USED to think it was all 70 degrees or was I on sum bum website?
Well, it ain’t the kind of place to raise your kids
In fact it’s cold as hell.
Bum website!
But remember also that the definition of the temperature of a virtual vacuum will differ somewhat from the definition of a medium.
I suggest that you read up on the subject.
