Sight velocity

In astronomy, the velocity dispersion (σ) is the statistical dispersion of velocities about the mean velocity for a group of astronomical objects, such as an open cluster, globular cluster, galaxy, galaxy cluster, or supercluster. By measuring the radial velocities of the group's members through astronomical spectroscopy, the velocity dispersion of that group can be estimated and used to derive the group's mass from the virial theorem. Radial velocity is found by measuring the Dopple… WebMay 8, 2024 · The cluster is on a circular orbit around the Galactic centre with a true orbital velocity v (shown as a vector). We measure the component of this in our line of sight as …
