Dear dialists,
I have heard and seen pictures of that sundial placed
in Mars but I have never heard of a sundial on the Moon...
Does anybody know something about this?
Such a sundial would be 'more or less' similar to one
on the Earth... except for the small wobbling of the
Moon's orbit (around 5,5 deg) on the equator's plane
which would mess the hour lines.
But I am waiting for NASA to send a spaceship to
Mercury's surface, because a sundial there would
be most curious... do you guess why?
Best regards,
Anselmo Perez Serrada
You're probably referring to the fact that there are only (and exactly)
1.5 'days' in a 'year'!
The equatorial inclination is apparently small, so there would be much
less declination effect, but the eccentricity is very high.
Should be quite a challange to lay out...
Dave
