I had thus learned a second fact of great importance: this was that the planet the little prince came from was scarcely any larger than a house!

But that did not really surprise me much. I knew very well that in addition to the great planets—such as the Earth, Jupiter, Mars, Venus—to which we have given names, there are also hundreds of others, some of which are so small that one has a hard time seeing them through the telescope. When an astronomer discovers one of these, he does not give it a name, but only a number. He might call it, for example, “Asteroid 325.”
