Mercury's Day and Year
Name: Ben C.
Why is Mercury's year faster than its day? Is this just one of those thing
that seem to happen?
The rotational period of the planets continues to approach its revolutional period due to
something called tidal friction. In other words, at some theoretical time in the future
(maybe after the sun ceases to exist!) all the planets would have one rotation for every
revolution. You might wish to read up on it.
