Final answer:
Halley's Comet remains within our solar system, orbiting the Sun on a highly elliptical path every 76 years, with its next return anticipated in 2061.
Step-by-step explanation:
No, Halley's Comet does not leave our solar system. As a short-period comet, it is a permanent member of our solar system, with a highly elliptical orbit. The comet's journey around the sun takes about 76 years, with its farthest point being beyond the orbit of Neptune. While comets can be ejected from the solar system or destroyed by the sun or a planet, this has not been the case for Halley's Comet. Historical records since 239 BCE have chronicled every passage of Halley's Comet near the Sun at regular intervals, which vary slightly due to gravitational perturbations from the planets. Its next expected return is in the year 2061.
