SOMNITEL'NY' SERP ZEMLI
Kniga V. Stepanova "Serp zemli" zakanchivaetsya tak: "Plyvi pod solnechnym vetrom, shar goluboi! I on vse uplyvaet, vse taet v zvezdnyh dalyah. I vot uzhe visit v podnebes'e siyayushii serp Zemli..." (tam zhe, str. 77). Eta kartina myslennogo sozercaniya togo, kak Zemlya udalyaetsya v zvezdnye dali, tozhe neverna. V takih sluchayah kruglyi disk Zemli stanovilsya by vse men'she i men'she i, nakonec, prevratilsya by v obyknovennuyu zvezdu. Serp Zemli mozhno uvidet' lish' v tom sluchae, esli chelovek budet nablyudat', ne udalenie Zemli v beskrainie dali, a ee obrashenie vokrug Solnca so storony, naprimer s Luny ili Marsa. Kogda Zemlya nachnet proletat' za Solncem, budet viden ee kruglyi disk. No vot planeta, obognuv dnevnoe svetilo, sprava nalevo, nachnet priblizhat'sya k nablyudatelyu, i togda on uvidit, kak kruglyi disk Zemli nachnet umen'shat'sya do poloviny. Drugaya polovina budet v teni. A uzh potom, kogda Zemlya budet prohodit' sleva napravo mezhdu Solncem i nablyudatelem, ona budet vidna nekotoroe vremya v vide serpa. Sledovatel'no, chtoby uvidet' serp Zemli, nado chtoby Zemlya ne udalyalas' v kosmicheskie prostory, a, obrashayas' vokrug Solnca, priblizhalas' k nablyudatelyu.
