Tycho Brahe rejected Copernicus's model primarily because he could not detect stellar parallax, which he expected to observe if the Earth was indeed orbiting the Sun. This absence of observable parallax was a significant argument against the heliocentric model at the time, as it suggested that either the stars were unimaginably distant (to make the parallax too small to detect with the naked eye) or that the Earth did not move.
