  To find its redshift, follow the instructions in

  #1 How do I : Find out more information about the galaxy I have classified? http://talk.galaxyzoo.org/#/boards/BGZ0000005/discussions/DGZ0000lv2
  Examine, Skyserver, Finding Chart, navigate, NED

  This galaxy hasn't had its spectrum taken, so there is no exact redshift.

  Click on PhotoZ and find its estimated redshift is

  z 0.02045
  zErr 0.017598

  To find its recessional velocity, look at Wolfram Alpha site for a calculator, look through these links for info.
