标题： Aten-Alinda orbital evolution: the example of possible interacting orbits

摘要： 887 阿琳达星和 2062 阿提恩星是典型的近地小行星 (NEA)。 我们之前的研究表明它们可能起源于地球轨道附近的灾变性碰撞。 这确定了本研究的目标——详细调查这些天体之间的相互作用。 小行星 887 和 2062 的轨道在近日点和远日点附近相交。 因此，这些天体的相互作用可能发生在一个显著的时间间隔内，并且持续时间相对较短。 由于多种原因，灾难性碰撞碎片的轨道可能没有精确的交点。 此外，在过去较大的轨道元素初始值不确定性会增加整合时的误差。 这些因素决定了结果的概率性质以及需要对灾难过程进行建模。 然而，由于轨道的特定空间位置，结果具有高度确定性的数值表达——在推测小行星 887 和 2062 可能的相互作用事件时，该事件大约发生在 1400 年前。 讨论了其他一些近地小天体（包括象限仪座流星雨）可能参与上述灾难性事件的可能性。 显示英文摘要

摘要： Minor planets 887 Alinda and 2062 Aten are typical near Earth asteroids (NEA). Our previous researches show their possible origin in catastrophic collision near Earth orbit. It is determine the target of present research -- to investigate interactions between these objects in more details. Orbits m.p. 887 and 2062 are crossed near pericenter and apocenter accordingly. So possible interval of the interaction of these objects is repeated through the significant time interval and has relatively small duration. On the strength of several reasons, orbits of fragments of the disastrous collision can have no an exact intersection. Besides, when integrating on the greater gap in the past increases a role of the uncertainty of initial values of elements of orbits. These factors determine a probabilistic nature of the result as well as need of modeling of the disastrous process. However, on the strength of the specific spatial location of orbits, result has highly determined numeric expression - in the suggestion on the possible interaction m. p. 887 and 2062, this event has occurred about 1400 years ago. The possible participation some other near Earth minor objects, include Quadrantides meteoric stream, in described disastrous event is discussed.
