Ordinary stars, not small ones.  But one must know which stars count
as "ordinary", which is why this siman is not given to everybody, and
why we were given the shiurim in units of how far one could walk (at
the equinox in EY).    And this shiur is based on a standard walker's
daily distance divided equally over the day, not on the state of the
individual's legs or on how much ground one could cover with a sudden
burst of energy.

                 return to all the places that have been given to them.
