korabl' NEAR stal pervym iskusstvennym
sputnikom asteroida.
NEAR byl uvlechen slaboi gravitaciei etogo 36-kilometrovogo bulyzhnika, obladayushego
formoi tufli. Segodnya na kartinke pokazan
pervyi snimok, kotoryi sdelali kamery korablya, kogda tot
podletel k asteroidu 433 Eros na 360 km. Na snimke razlichimy detali razmerom
30 metrov. V samom uzkom meste Erosa raspolozhen krater diametrom 4.8 km,
kotoryi pokazan krupnym planom na kartinke. Vnutri kratera vidny
udivitel'nye sloi i borozdy, a takzhe obodok kratera i gigantskih razmerov kamen',
50 m v diametre, lezhashii na dne kratera. Eros yavlyaetsya
krupnym asteroidom S-tipa, priblizhayushimsya k Zemle. Odnako on vse eshe ne tak
massiven, chtoby ego sobstvennaya gravitaciya sformirovala ego v sferu, kak dlya bol'shinstva
planet.
Po sravneniyu s Zemlei Eros obladaet lish' tysyachnoi dolei nashei gravitacii, t.e.
telo, kotoroe na Zemle vesit 40 kg, tam budet vesit' okolo 30 g.
Telo, broshennoe so skorost'yu 35 km v chas, pokinet asteroid i uletit v otkrytyi kosmos.
Slabaya gravitaciya i nepravil'naya forma etogo nebesnogo tela sdelali neprostoi zadachu kontrolya za dvizheniem
NEAR vokrug Erosa, poskol'ku sushestvuet godovaya programma issledovanii, v ramkah kotoroi
korabl' dolzhen ochen' blizko priblizit'sya s
poverhnost'yu asteroida.
