    For completeness, after the extreme lunar perigees, I have also calculated the extreme apogees. To notice as unlike the extreme perigees, the apogees are very less distant from the middle valor.

    A duo is a pair of eclipses separated by one lunation (synodic month). I have listed all duos from year 0 to 3000.
    In some rare years the duo is in the same month.

    According to the theory in one year there can be 2,3,4 or 5 solar eclipses, considering all type, total, partial, annular and hybrid, I have created a page with the eclipses divided in number for year.

    It's frequent an occultation of a planet by the Sun, but it's very rare that it happens during a solar eclipse. These events are not observable, I have calculated only for curiosity.

    If we define alignement the event when all planets have the same heliocentric longitude, from Mercury to Neptune, also if we neglet the differences in latitude and the orbital inclination.
    In the best case, we can consider that the planets can be in the same sector, a very narrow sector (heliocentric sector!), the minimum sector with 8 planets is only 43° in a time span of 9000 years

    The length of the synodic month is 29.5306 days. It would wait us therefore that the full Moon falls after 14.77 days and the first quarter after 7.38 days.
    But these are mean and very varying values. This is due to the fact that the Moonų

    A lunation is the time interval between two similar lunar phases (from New Moon to New Moon or from Full Moon to Full Moon). For this table I used from New Moon to New Moon, when the apparent geocentric ecliptical longitudes of the Moon and the Sun are equal. The mean duration of the lunation is 29d 12h 44m, but it is variable...

    Easter falls on the Sunday which follows the first Full Moon after the spring equinox. And lunar eclipses occur only at Full Moon!
    At first view this phenomena seems impossible, but we know that for the ecclesiastical rules the spring equinox is fixed at March 21 and
    that the Full Moon is taken from ecclesiastical tables. Sometimes the astronomical ephemerides differ from the ecclesiastical tables.

    1. Do you actually believe there is any software anywhere that can simulate the universe? (Here's a hint - there is not)
    2. Did you mean you want a software that can calculate the position of the stars and planets at different times and dates? (If you did that's what all Ricci's posts are about.)
    3. If neither of these, what did you mean.
    4. Consult a dictionary for the difference between simple and simplistic.

    Oppositions of Mars occur at an average interval of 780 days; because of the eccentricity of the orbits, opposition's date and least distance don't coincide, but can be as large as 9 days.
    In the favorable periheliac oppositions, Mars approaches the Earth within 0.4 astronomical unit; these oppositions repeat at intervals of 15 years or 17 years. Each opposition is followed by a very similar one 79 years later.
    Mars has a risonance with the Earth of 79 years (15+15+15+17+17) or 284 years or 363 years.

    In very rare occasions Mercury transits on the Sun with only a part of its disk or rather the least separation between the centers of the two bodies it is slightly superior in comparison to the solar radius.
    The last event is happened on November 15th 1999, but for the next we must attend six centuries.

    Usually a solar eclipse, total or annular, is preceded or followed by a lunar eclipse (a partial or one/two penumbral).
    In very rare case a total o annular solar eclipse is accompanied by a lunar total eclipse
