Nyanzvi dzomuchadenga dziri kuwana mapuraneti matsva zuva nezuva. Panogona kuva nemabhiriyoni emapuraneti ari muchadenga. Enzanisa aya mapuraneti akawanwa negadziriro yedu yeZuva.
Musiyano mukuru uripo pakati peGadziriro yedu yeZuva nemapuraneti ari kure ndiwo unoita sokuti ndiwo musiyano uri pakati pemapuraneti aya nemapuraneti ari pedyo nawo. Mapuraneti ari muSolar System yedu ane madenderedzwa maduku maduku (ane eccentricities <10% kubva pane imwe nzvimbo yakakwana), nepo exoplanets ane kusvika ku50% eccentricities. Exoplanets dzine eccentrictes dzakakwirira dzingave dzisina kugadzikana kwenguva refu. Mumwe musiyano ndewokuti ukuru hunozivikanwa zvikuru hwemaexoplanets i"super earth" (iyo iri 2-3x ukuru hwepasi) nepo zuva redu risina super earth.
