Poyasnenie:
V poslednee desyatiletie bylo sdelano
nadezhnoe otkrytie
mnozhestva planet vne Solnechnoi sistemy, i ni odna iz nih ne pohozha na
nashu Zemlyu. S pomosh'yu
tochnyh nablyudatel'nyh metodov
astronomy otkryli bolee, chem dve dyuzhiny
vnesolnechnyh planet,
massy bol'shinstva kotoryh sootvetstvuyut massam planet-gigantov takih kak
Yupiter i tyazhelee. Konechno zhe sushestvuyut i menee massivnye planety. Tak, vchera
iskateli eshe
nerozhdennyh planet zayavili o tom, chto skoro budut otkryty dve novye
planety razmerami s Saturn. Zvezdy, vokrug
kotoryh eti planety dvizhutsya, eto 79
Kita
na rasstoyanii 117 svetovyh let ot Solnca i HD46375 v sozvezdii
Edinoroga
na rasstoyanii 109 svetovyh let. Massa pervoi planety sostavlyaet po krainei
mere 7/10 massy Saturna, a ee
orbita
prolegaet na srednem rasstoyanii 52 milliona km ot 79 Kita. Sravnite s odnoi
astronomicheskoi edinicei - rasstoyaniem
ot Zemli do Solnca - 150 millionov km. Etot zahvatyvayushii risunok hudozhnika
demonstriruet svezheotkrytye planety s kol'cami i sputnikami, t.e. pohozhimi na
planety-giganty nashei Solnechnoi sistemy. Planeta u HD46375 imeet massu 8/10
massy Saturna i obrashaetsya na rasstoyanii 6 millionov km ot nee.
Massa
Saturna
sostavlyaet tret' massy
Yupitera
i 100 mass Zemli. Udivitel'nye nahodki v
poiske men'shih planet
eshe zhdut nas.
