<p>Well as late as 1942, with a reference to book <em>The Little Prince,</em> by Antoine de Saint-Exupéry, we didn't even know the correct shape of asteroids, believing them to be round like planets.

<p>Mark Twain could have been referring to quite a few objects with the unclear definition of asteroids.</p>

Thank you. No matter which object Twain was referring to, he certainly knew enough to state that the asteroid is a huge object (compared to a hen's egg).

<p>When was the nature and size of asteroids discovered? I was under the impression that it was not until the 1980s or 1990s with deeper space probes and Hubble imagery that we learned the nature of asteroids.

Twain was born under a comet and died under a comet. That probably has something to do with any anachronistic knowledge of his :P

You see a comet. You wanna reach it with your hands. No go. You climb a mountain. You wanna reach the comet with your hands. No go. You deduce the comet is far away. You leave a chicken's egg on the mountain and look at it when you descent. You realize the comet appears larger than the chicken's egg does. You have just deduced that the comet is a lot larger than the chicken's egg.
