One is a rocky planet 1.5 times the size of Earth. The other is a gaseous world nearly four times Earth's size. Together they form a spectacular system in which two planets orbit closer to each other than any yet discovered.
"We've never known of planets like this," said Yale University astronomer Sarbani Basu, a member of the research team that analyzed the system. "If you were on the smaller planet looking up, the larger planet would seem more than twice the size of Earth's full moon. It would be jaw-dropping."

It's just that we do seem to assume a great deal about the size and distances involved without considering that it might all be a bit wrong perhaps?
