Introduction
Modern telescopes and satellites are more than capable of detecting celestial objects from across the visible universe, and are able to collect extensive colour and brightness magnitude data on all of them using advanced tools and technologies. However, the largest roadblock to completing the catalogue, is our own Sun itself. It is far too close and bright, causing every lens pointed at it to completely malfunction and fail to gather any accurate measurements.
Nonetheless, there is a way to get this information, and it is to look towards other stars in the night sky that share extremely similar properties to our own, known as solar twins. Previous research studies have found hundreds of these "twins" that are almost identical to Sol, and the GAIA satellite launched by the ESA has the exact measurements we are looking for identified in the twins. Using regression analysis of the slight variations within each star, a precise estimation of Sol's colour and magnitude was found across a variety of colour bands.
