The super-dense world circles so close to its host star that it takes a mere 18 hours to complete one orbital lap. Using our solar system for comparison, 55 Cancri e is 26 times closer to its parent star than Mercury is to the sun, according to NASA officials.

These poor writers. 26 times a distance is not the same thing as 1/26 of the distance. You can say something is X times as far, but not X times as close.

So, either "Using our solar system for comparison, Mercury is 26 times farther away from the sun than 55 Cancri is to its parent star" or "Compared to Mercury's distance from the sun, 55 Cancri is only 1/26th that distance from its parent star."

I vacationed here two years ago. Drink only bottled ammonia, the local tap ammonia is not safe. The locals pray to an idol they call ‘Soetoro’. The food is terrible and watch out for the two-headed women in the bars.

Sunrise on 55 Cancri e must be an awsome sight.
