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."

If a world is “super dense,” does that mean that earth bullets would bounce off you, or that it is inhabited by democrats?

Yeah, that’s a common problem, the x times = 1/x, math is just not their strong suit. It’s possible that they’re dumbing it down for their readers, but I’m pretty sure their readers aren’t that dumb.

First there’s the ooze, then there’s the running and screaming...

18hrs... wonder how fast that means it's traveling

Does it mean that gravitational pull is increasing its orbit speed and it already burned up in that star 40 or less years ago?
To: Deaf Smith
now there's a thought...

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.

Second thought is the planet's own rotation is about 18 hours, thus only one side faces the star in our observation. We are only seeing the 'Dark Side' as is the example of our Moon?
To: Chode
Assuming a circular orbit at 1,385,000 miles (=36,000,000/26) we get an 8,700,000 mile orbital path. The 18 hour period implies a speed of about 483,000 miles per hour. That is about 7.25 times as fast as the Earth revolves around the Sun.
To: 17th Miss Regt
thx... but wouldn't that be 24hr*365days=8760hrs per year/18hrs=486.6666 times as fast as the earth?
