We selected ONC candidate stars for which the probabilities of belonging to the cluster were estimated. Using Gaia DR3 star parallaxes, we determined the distance of the ONC from the Sun to be 393 ± 13 pc. The analysis allowed us to estimate the number of single and binary stars, the number of stars with planets, and the number of free planets in the selected region of space in the central part of the ONC. Our estimates indicate the possibility of obtaining new results from numerical modeling.</p></abstract><trans-abstract xml:lang="ru"><p>По данным Gaia DR3 проведено исследование Скопления Туманности Ориона (ONC) в области неба, где с помощью телескопа Джеймс Уэбб (JWST) обнаружены свободные планеты и звезды с планетными системами. Отобраны звезды — кандидаты в состав ONC, для которых оценены вероятности принадлежности скоплению. По параллаксам звезд Gaia DR3 определено расстояние ONC от Солнца, равное 393 ± 13 пк. Анализ позволил оценить число одиночных и двойных звезд, число звезд с планетами, число свободных планет в центральной части ONC. Полученные оценки свидетельствуют о возможности получения новых результатов численного моделирования.</p></trans-abstract><kwd-group xml:lang="en"><kwd>ONC</kwd><kwd>M 42</kwd><kwd>open star clusters</kwd><kwd>Orion Nebula Cluster</kwd><kwd>ONC</kwd><kwd>M 42</kwd><kwd>exoplanets</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рассеянные звездные скопления</kwd><kwd>Скопление Туманности Ориона</kwd><kwd>экзопланеты</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>S.G.
