How would you guess Isaac Mizrahi and a chipper QVC host might fare on a pop quiz of astronomy basics? If your answer was “poorly,” you are totally correct. While shilling his wares on the channel yesterday, the designer encountered an obstacle in the form of two prominent members of our solar system. Pointing to a green top with a swirling print, the host said, “It almost kinda looks like what the Earth looks like when you’re a bazillion miles away, from the planet Moon.” As often happens when you get into Space Talk, the conversation only gets more intense from there. “Is the moon a star?” she asks. “No, the moon is a planet, darling. The moon is a planet, honey,” Mizrahi responds in a confident, if a bit mansplain-y manner. He’s less clear on the role of the sun, though. “I don’t know what the sun is,” he admits. We can only hope that on the next episode, Neil deGrasse Tyson comes on to clear all of this up.
