Controversies about the value of the third cosmic velocity

Stanisław Hałas, Adrian Pacek

Abstract


The purpose of writing this article was to derivate the formula for the third  cosmic  velocity using  only  the  laws  of  conservation  in  the  heliocentric  reference  system.  It  turns  out  that  it  can  be done  by  using  elementary  mathematics,  thanks  to  which  the reasoning  and  calculations  are  affordable  for  one  interested  in  this  subject.  By  the  way,  we  wanted  to  discuss  the  errors  that  appear  even  in  well-known  textbooks  and  professional  articles,  whose  commitment  leads  to  incorrect  results.  The  magnitudes  of  the  third  cosmic  velocity  obtained  by  us  are:  v3average  =  16.68  km/s,  v3perihelion  =  16.57  km/s  and  v3aphelion  =  16.79  km/s.
