Ça ne pouvait pas étonner beaucoup. Je savais bien qu’en dehors
des grosses planètes comme la Terre, Jupiter, Mars, Venus, auxquelles on a donne des
noms, il y a des centaines d’autres qui sont quelquefois si petites qu’on
a beaucoup de mal à apercevoir au télescope. Quand un astronome
découvre l’une d’elles, il donne pour nom un numéro. Il
appelle par exemple : « l’astéroïde 3251 ».
