Comet Nearly Hit Earth? Not So Fast

Posted by timothy

Phil Plait ("The Bad Astronomer") writes with a skeptical take on the recent report that a comet may have narrowly missed earth. According to the linked post from Plait, "When a comet breaks up, it spreads out. Even when intact, the material surrounding a comet can be tens or even hundreds of thousands of kilometers across! Claiming that a comet broke apart, yet managed to constrain its pieces to volume of space less than a few thousand kilometers across strains credulity. Mind you, Bonilla claimed to have seen these objects over the course of two days. That means they would’ve been stretched out along a path that was a million km long at least, yet so narrow that only one observatory on Earth saw them transit the Sun. That is highly unlikely. Worse, the very fact that no one else saw anything makes this claim even less tenable."
