    Hopefully someone can answer this litle question of mine. Since Mercury orbits the sun in only 88 days, why can we see transists more often than about 13 times a century (according to space.com)?

    I'm no expert in these matters, but maybe the transits occur primarily at night when the sun is switched off. This would make sense because Mercury would probably catch on fire if it were to pass so close to the sun while it were hot.

  30. Mercury passes Earth 4 times an earth year by Tired_Blood · · Score: 1

    Here's another reason why it's rarer than you'd first assume:
    Mercury orbit: 88 days.
    Earth orbit: 365 days.
    Mercury is 4.14772 times faster than Earth. However, that doesn't mean that it's passes Earth 4.14772 times in an Earth year.

    Instead of working out the math using these two rates, think of a 12 hour span and a truely analog clock. The minute and hour hands overlap at the following specific times:
    t=12:00 exactly (first pass)
    t=between 1:05 and 1:06 (second pass)
    t=between 2:10 and 2:11 (third pass)
    t=between 3:16 and 3:17 (fourth pass)
    t=between 4:21 and 4:22 (fifth pass)
    t=between 5:27 and 5:28 (sixth pass)
    t=between 6:32 and 6:33 (seventh pass)
    t=between 7:38 and 7:39 (eighth pass)
    t=between 8:43 and 8:44 (ninth pass)
    t=between 9:49 and 9:50 (tenth pass)
    t=between 10:54 and 10:55 (eleventh pass)
    t=between 11:59 and 12:00 (twelvth pass)
    But, the twelvth pass is not technically correct, since it really is 12:00 or the first pass. Even if it were, then the twelvth and first pass would occur in the same "pass".

    Therefore, in a 12 hour span (on average), the minute hand passes the hour hand 11 times, even though it's 12 times faster (12 revolutions of the minute hand for 1 revolution of the hour hand). It's a tricky question that I haven't heard in a very very very long time.

    This issue would only account for about 1/4 of the "missing" Mercury passes, but that's a big amount of error anyway. When you look at the missing Venus passes, since the orbits are much closer in time, the assumption error (described above) is significantly larger.

    This is aside from any other mis-alignment factors such as planetary inclinations.
