Maow writes ""This object was discovered during a scan that covered the equivalent of 1,000 times the [area] of the full moon," said study co-author Etienne Artigau of the University of Montreal.
"We observed hundreds of millions of stars and planets, but we only found one homeless planet in our neighbourhood."
This planet appears to be an astonishingly young 50-120 million years old.
The paper is published at arxiv.org.
Here's hoping the Mayan End-of-World-2012 people don't seize upon this as some kind of impending rogue planet on a collision course with Earth, but one can expect it'll be bantered about on such forums."
