Question
An object is 42600 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.
Transcribed Image Text:An object is 42600 AU away from you.

Expert Solution
Step 1

Given that.

Distance of the object = 42600 AU

  • 1 AU = 1.496 x 1011 m
  • 1 AU = 1.496 x 108 km (because 1 m = 10-3 km)
  • 1 AU = 2.345 x 104 Earth's radii
  • 1 AU = 1.581 x 10-5 light years
  • 1 AU = 4.848 x 10-6 Parsec
