The author investigates whether the adoption of a value of the solar parallax determined by radar measures would permit an acceptable representation of the observations of Eros. The solution he obtaines leaves important residuals and leads to a rather unlikely value for the mass of Mars.

Résumé. — L'auteur pose le problème de savoir si Fadoption d'une valeur de la parallaxe solaire telle qu'elle a été déterminée par radar, permet une représentation convenable des observations d'Éros. La solution qu'il obtient donne des résidus importants et une valeur peu vrais semblable de la masse de Mars.

Zusammenfassung. — Verf. untersucht die Frage, ob die Annahme eines Wertes für die Sonnenparallaxe, der durch Radarmessungen bestimmt wurde, eine annehmbare Darstellung der Erosbeobachtungen gestatten würde. Bei der erhaltenen Lösung bleiben wesentliche Residuen, in Verbindung mit einem recht unwahrscheinlichen Wert für die Marsmasse.

Резюме. — Автор ставит следущую задачу: может-ли принятие значения солнечного параллакса определенного радаром позволить удовлетворительные представления наблюдений Epoca ? Полученное решение дает значительные остатки и мало вероятное значение массеь Марса.
