[OS X TeX] Spacing of first two rows in tabular environment

Hi,

This isn't Mac specific, but it's something that's bugged me for a
LONG time, and maybe someone can help me out. I've always felt that
the second row of a table is too close to the horizontal rule (if any)
that separates it from the top row. For example, when I typeset the
table below in 11pt Lucida, the exponents touch the horizontal rule.
Is there a simple, non-kludgy fix or adjustment for this? I don't want
to increase all the linespacing, just the spacing between the first
and second row. Thanks.

Chris

The table:

\begin{center}
\begin{tabular}{lccc}
Planet & Mass (kg) & Distance from Sun (km) & Period of Orbit (years) \
\\hline
Earth & $5.98\times10^{24}$ & $1.50\times10^8$ & 1.00 \\
Venus & $4.87\times10^{24}$ & $1.08\times10^8$ & 0.615 \\
Mars & $6.40\times10^{23}$ & $2.28\times10^8$ & 1.88
\end{tabular}
\end{center}
