WebbIndeed, it may be possible to use the size of the Milky Way as an extra-galactic "meter stick" and determine distances to similar spiral galaxies. More than eighty years after Shapley published his estimate of Ro, there is a reasonable consensus as to its value. Nearly all methods of determining Ro now yield values between 7 and 9 kpc.

Distances expressed in fractions of a parsec usually involve objects within a single star system. So, for example: • One astronomical unit (au), the distance from the Sun to the Earth, is just under 5×10 pc. • The most distant space probe, Voyager 1, was 0.000703 pc from Earth as of January 2024 . Voyager 1 took 41 years to cover that distance. WebbIn 1917 Harlow Shapley decided to measure the size of the Milky Way by finding the distance to special star clusters called globular clusters using a variable star period-luminosity relation. ... He found that the clusters were distributed in a spherical cloud with radius at least 10 kpc. The centre of this cloud is not at the Sun.

WebbA satellite like Tucana 3, with pericentre ~3.5 kpc, must have a core size smaller than ~2 pc to survive just three orbital periods on its current orbit. ... orbits with small pericentric radii would strengthen these conclusions and allow for stricter upper limits on the core sizes implied by the survival of Milky Way satellites.
