The great thing about films like Interstellar is that it gets our curious citizenry interested in space exploration again. The eternal, unfathomable questions, like "What is on the other side of a wormhole?" or "Can we ever travel faster than the speed of light?" or "Is the Moon a planet or a star?"
That last one, perhaps the most troubling of all space questions, plagued QVC host Jane Treacy and fashion icon Isaac Mizrahi while trying to sell some ugly splotchy blouses.
(For the record, the Moon is a moon. It's in the title of the thing that it is. The sun is a star. They got that one right. Partial credit.)
You can watch the full video from QVC's channel below. The planet/moon/star quandary starts around 7:20.
