Question
An object is 82200 AU away from you. What is this distance in... meters (m) kilometers (km) Earth radii (Re) light-years (ly) parsecs (pc) Note: the point of this problem is to practice unit conversions, not to Google them; all the conversion factors are given in Appendix E, page 1079 of Astronomy 2e. It will be handy to convert AU to m first, and then use that for your other answers, rather than starting from AU. Be careful of cumulative rounding errors.

Expert Solution
Step 1

Answer)

It is a simply unit conversion based question.

Given distance is 82200 AU

  • 1 AU = 1.496 x 1011 km and 1 m = 10-3 km

         So, 1 AU = 1.496 x 108 km

  • Earth radius = 6371 km = (6371)/(1.496 x 108) = 4.26 x 10-5 AU  (because 1 AU = 1.496 x 108 km )
  • 1AU = 1.58 x 10-5 Light years and
  •  1AU = 4.85 x 10-6 Parsec
