The following file runs without problems:

\documentclass{article}
\usepackage{makeidx}
\makeindex
\usepackage{hyperref}
\begin{document}
Hello\index{semi-major axis}
\printindex
\end{document}

Probably you have something like

  \index{foo|semi-major}

That means, that the page number of "foo" should be formatted
with command "\semi-major". See the documentation of Makeindex.

Thus check page 124 for \index commands with "semi-major" and "|".
