A summary of these methods: 1  Cepheid variable stars and their cousins the RR Lyrae stars are the primary distance indicators in the galaxy and the local group. 2  They pulsate radially (basically at the sound speed in the envelope of the star) with a period inversely proportional to the square root of the density.
Much better! Ok fastest large scale object: by using Hubble's logic, the fastest Galaxies are those which are farthest away - the farthest confirmed Galaxy is MACS0647-JD, which has a redshift of 10.6 - which gives a velocity relative to Earth of 0.98c.
