Posle togo, kak "Voyadzher-1" posetil vneshnyuyu chast' solnechnoi sistemy,
poluchiv krasivye fotografii dal'nih planet, on "posmotrel" vnutr'
solnechnoi sistemy. Venera, Zemlya, Yupiter,
Saturn, Uran i Neptun byli vidny na nebe. Tol'ko
teper' vse oni byli malen'kimi svetyashimisya pyatnami, bolee slabymi, chem mnogie zvezdy.

Nad proishozhdeniem solnechnoi sistemy lyudi uzhe davno razmyshlyayut. Tol'ko
vot obshaya kartina etogo yavleniya ne yasna do sih por. Vozmozhno, chto
pervonachal'no bylo tol'ko sem' planet, Neptun, Uran, Saturn, Yupiter,
Mars, Zemlya i Venera. Byli takzhe disk asteroidov i komety.Zatem na
opredelennoi stadii evolyucii solnechnoi sistemy ona ispytala moshnoe
vozmushenie, kotoroe nikto nikogda ne uchityval. Eto vozmushenie
sohranilos' v strukture solnechnoi sistemy v nekotoryh nablyudaemyh
anomaliyah. Naprimer, Pluton, veroyatno, byl sputnikom Neptuna, a Merkurii
byl yadrom Venery. Vozmushenie orbit asteroidov privelo k ih chastym
stolknoveniyam, chto stalo istochnikom meteoritov. Solnce poteryalo bol'shuyu
chast' uglovogo momenta. Protooblako Urana izmenilo naklon osi vrasheniya.
Poyavilos' massivnoe ledyanoe telo, kotoroe cherez mnogo let upalo na
rasplavlennuyu Zemlyu, v rezul'tate chego poyavilas' Luna, a na Zemle voda i
zhizn'. Tak chto est' osnovaniya dlya razmyshlenii.
