Do parallax angles of distant stars too small to measure? - Answers

Yes, for very distant stars, parallax angles become exceedingly small and challenging to measure accurately. As the distance increases, the apparent shift in a star's position against more distant background stars diminishes, making it difficult to detect with current instruments. This limitation means that while parallax is effective for nearby stars, astronomers often rely on other methods, such as standard candles or redshift measurements, to determine distances to faraway stars and galaxies.
