Yes, the position of our solar system is constantly changing due to various factors. However, over the course of a few centuries, the changes in the position of our solar system are relatively minor on a cosmic scale. Here are a few factors to consider:
Galactic Motion: Our solar system is part of the Milky Way galaxy, which itself is in motion. The Milky Way rotates, and as a result, the position of the solar system within the galaxy changes gradually over time. However, these changes occur over millions of years rather than centuries.
Orbital Motion: The solar system orbits the center of the Milky Way galaxy. It takes approximately 225-250 million years to complete one orbit, known as a galactic year or cosmic year. Within this timescale, the position of the solar system will undergo significant changes. However, over a few centuries, the impact of orbital motion is minimal.
Interactions with Other Stars: The gravitational influence of nearby stars can cause slight perturbations in the motion of our solar system. However, the effect of individual stars is typically small and unlikely to cause significant changes in a few centuries.
Local Interstellar Environment: The solar system moves through interstellar space, encountering different regions of gas, dust, and other celestial objects. These encounters may affect the solar system's motion and environment, but their impact on the position of the solar system within a few centuries is generally limited.
Overall, while our solar system is in motion and its position changes over vast timescales, the changes observed within a few centuries are relatively minor. The long-term evolution and trajectory of the solar system require much longer timescales to become apparent.
