'The line is getting fuzzier': Asteroids and comets may be more similar than we think

As anyone who has ever tried to clean a home knows, ridding yourself of dust is a Sisyphean effort. No surface stays free of it for long. It turns out that space is somewhat similar. Space is filled with interplanetary dust, ...
