Do blizhaishih zvezd - izmeryayut godichnyiprallaks. Etot princip primerno ekvivalenten principu binokulyarnogo zreniya, tol'ko rasstoyaniem mezhdu "glazami" v dannom sluchae vystupaet diametr orbity Zemli. Poryadok velichiny godichnogo parallaksa (t.e. izmeneniya uglovyh koordinat blizhaishih zvezd na nebesnoi sfere v techenie goda) doli uglovoi sekundy. Otsyuda zhe edinica mezhzvezdnyh rasstoyanii parsek - parallaks-sekunda (tri s nebol'shim svetovyh goda).
V sluchae planet ihvidimoe polozhenie otnositel'no zvezdzametno menyayutsya uzhe pri izmenenii polozheniya nablyudatelya pri vrashenii Zemli ili sudalennyh drug ot druga tochek poverhnosti Zemli- princip tot zhe samyi.
V osnove etih metodov - tochnye izmereniya polozheniya planet iSolnca otnositel'no zvezd i zvezd otnositel'no drug druga. Pri etom uzhe nuzhno uchityvat' popravki, vyzvaemye, v chastnosti, dvizheniem Zemliv prostranstve i konechnost'yu skorosti sveta.
No gorazdo bol'shuyu tochnost' daet izmerenie rasstoyanii do blizkih ob'ektov metodami radiolokacii (v tom chisle do Solnca i planet).
