In recent decades, there have been opportunities to use the concept of central configurations also in theoretical physics, chemistry, crystallography, etc. We consider planar central configurations, called nested, consisting of polygons sequentially nested one into another, at the vertices of which there are bodies (material points). The existence of nested planar central configurations of trapezoidal type with a sphere in the centre is proved. Early, it was found that abovementioned isolated central configurations exist in the heliocentric rotated coordinate systems. It was supposed only the Newton’s law of attraction is acting between bodies. The Maple software is used to derive the solution of this problem.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">Изучение центральных конфигураций, понятия и определения которых были сформулированы уже классиками небесной механики - Эйлером, Лагранжем, Лапласом и Лиувиллем в XVIII-XIX вв., представляет интерес не только для небесной механики, но и для многих разделов математического анализа, дифференциальных уравнений, аналитической механики, звездной динамики и динамики космического полета. В последние десятилетия наметились возможности использования понятия центральных конфигураций также в теоретической физике, химии, кристаллографии и др. Рассматриваются плоские центральные конфигурации, названные гнездовидными, состоящие из последовательно вложенных один в другой многоугольников, в вершинах которых находятся тела (материальные точки). Доказано существование гнездовидных плоских центральных конфигураций трапециевидной формы с шарообразным телом в центре. Ранее было установлено, что изолированные плоские трапециевидные центральные конфигурации существуют во вращающихся гелиоцентрических системах координат. Предполагается, что на систему действует только закон притяжения Ньютона. В качестве средства решения задачи применена система компьютерной математики Maple.</p></trans-abstract><kwd-group xml:lang="en"><kwd>celestial mechanics</kwd><kwd>Maple software</kwd><kwd>nested configurations</kwd><kwd>trapezoidal configurations</kwd><kwd>spherical central body</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>небесная механика</kwd><kwd>программный пакет Maple</kwd><kwd>гнездовидные конфигурации</kwd><kwd>трапециевидные конфигурации</kwd><kwd>сферические центральные тела</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The work is in part supported by the Russian Foundation of Basic Research (Grant 13-01-0059)</funding-statement><funding-statement xml:lang="ru">Работа выполнена при частичной поддержке&#13;
