An object is 91900 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

As we know that

1 AU = 149597870691 m

So

91900 Au = 13748044316502898 m

In km

1Au = 149597870.69km

So 91900 Au = 13748044316503 km

In earth radii

1AU = 23454.706481 earth radii

So 91900Au = 2155487525.6 earth radii
