Abstract
Some asteroids, comets, and planets (ACPs) are accelerated by giant planets and ejected from parent planetary systems with velocities of several kilometers per second. When leaving a disintegrating stellar cluster rather than only a parent star, ACPs form a spear-shaped cloud in space. Thereby, ACP spears are formed at the Sun, stars, and stellar clusters. Consequently, due to ACP spears, the boundaries of planetary systems are expanded to dozens of kiloparsecs in the course of time. This paper is focused on the numerical analysis of the orbital evolution of unbound ACPs in the Galaxy, which leads to their transformation to “cometary spears” near the Sun, stars, and stellar clusters. It has been shown that, over time, the ACP spears of stars are transformed to the rings around a center of the Galaxy.
