Abstract
Here we statistically evaluate recent advances in determining the Sun-Galactic Center distance (Rsun) as well as recent measures of the orbital velocity around the Galactic Center (Vlsr), and the angular rotation parameters of various objects. Recent statistical results point to Rsun =8.0±0.2 kpc, Vlsr =230±3 km/s, and angular rotation at the Sun (ω) near 29±1 km/s/kpc for the gas and stars at the Local Standard of Rest, and near 23±2 km/s/kpc for the spiral pattern itself.
