Pitch Black ... for real :)

A world without night? Certainly possible given that LTT 1445b zips in a tight orbit around the biggest star in a triple-star system just 22.5 light-years from Earth, "transiting" between Earth and its host star on each pass. 

It gets better ...

Standing on the surface of the planet, which orbits its star at just one-tenth the distance between the sun and Mercury, "you'd see one big orange sun and two much smaller orangey-red suns in the distance," said Jennifer Winters, lead author on the study and an astronomer at the Harvard-Smithsonian Center for Astrophysics. "The primary star would look really big in the sky. It's really close. The other two are much farther away. They'd look about 100 times brighter than Venus, and about the same … size in the sky."

So ... does LTT 144b experience night? One never knows, do one. Pitch Black comes to mind from this rube's perspective as the planet depicted in the flick also has 3 suns. :)

Are you afraid of the dark?
