Line 2: The '''photometric parallax method''' is a method of data analysis used in [[astronomy]] that uses the colours and apparent brightnesses of stars to infer their distances. It was used by the [[Sloan Digital Sky Survey]] to discover the [[Virgo super star cluster]]. Unlike the [[~~parallax#Stellar_parallax\|~~stellar parallax]] method, photometric parallax can be used to estimate the distances of stars over 10 kpc away, at the expense of much more limited accuracy for individual measurements. Strictly speaking, it does not actually employ any measurements of parallax and can be considered a misnomer. == References ==
