A star with no measurable parallax is very close to Earth. The statement is FALSE because Parallax angles of less than 0.01 arcsec are too difficult to measure from Earth because of the effects of the Earth's atmosphere, <span>only the </span>closer<span> ones have a </span>parallax<span> that is large enough to be measured, a</span>nd the diameter of the Earth's orbit is small compared to the distance to all but the nearest stars.
