Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Mucherechedzi wezvinhu zviri muSolar System, Schiaparelli akashanda pane nyeredzi mbiri, akawana guru guru-bhandi asteroid 69 Hesperia musi wa 29 April 1861, uye akaratidza kuti mvura yemameteor yakabatanidzwa nemakometi. Akaratidza, somuenzaniso, kuti nharaunda yeLeonid meteor shower yakawirirana neiyo yekometi Tempel-Tuttle. Kucherekedza uku kwakatungamirira nyanzvi yokuongorora nyeredzi kugadzira fungidziro, yakazobvumikisa kuva yakarurama, yokuti mvura yemameteorite yaigona kuva nzira dzemakometi. Akanga ariwo mucherechedzi anodisa wemapuraneti omukati Mercurio neVenus. Akagadzira mifananidzo inoverengeka ndokuziva nguva dzayo dzokutenderera. Muna 1965, zvakaratidzwa kuti kuyerwa kwake uye kwakawanda kwakazotevera kwenguva yaMercury kwakanga kusina kururama. Akanga ari wokutanga kuziva kuti zviyero zvakaenzana zveEudoxus weCnidus naCallippus, kusiyana nezvakashandiswa nevazivi venyeredzi vakawanda venguva dzakazotevera, zvakanga zvisingafaniri kutorwa sezvinhu zvenyama, asi sechikamu chealgorithm yakafanana nemazuva ano Fourier series.  Mubvunzo: Schiaparelli anozivikanwa kuva akaratidza kubatana kwemvura yemameteor nechii?
