The cosmological distance ladder
... The bottom line is that from a redshift of z = 0.01 to 0.1 (recessional velocity 3000 to 30,000 km/sec) one can use the radial velocity of a galaxy to determine its distance. Beyond z = 0.1 one needs to know the mean density of the universe and the value of the cosmological constant in order to get ...

The Size of the Solar System
... As you can see, even when expressed in the one of the largest units (km) used to describe Earthbound distances, the sizes of and distances to the planets require numbers raised to large powers of ten.
