"The exact positions of stars change over time due to several factors, though these changes are often subtle and require long timescales or precise measurements to notice.
Timescale and Observation: Most of these changes are imperceptible to the naked eye over a human lifetime. Constellations like the Big Dipper look stable, but over tens of thousands of years, their shapes will distort significantly due to proper motion. Astronomers use precise instruments (like those on the Gaia spacecraft) to track these shifts, which are measured in milliarcseconds per year for most stars."
