    Super moon Monday 11/14/16 . Full moon's closest approach in 70 years.

    At my age I probably won't be around then.

    Give it a go! I anticipate the first manned landing on Mars that year. I am holding on for that, so we get two for the price of one.

    Sounds great, I hope it works.

    ... by such a small margin that it makes very little difference.

    There are a few similar full moons each year which are significantly brighter than average. You won't be able to tell the difference without advanced equipment.

    Not true, the angular size difference is quite apparent:

    Sorry, I meant that this particular "best since whenever" super moon is not going to look particularly different from other super moons without the use of advanced equipment.

    The difference between a super moon and an average or apogee moon is much more easily seen, especially in photos as you've illustrated, and also visibly affects the brightness.

    Took a look outside last night but it didn't seem much larger. Maybe needs to be closer to the horizon. hmmm

    I took a look at it last night .
    Real beautiful and bright. I could see it was apparently larger than usual full moons; but then again I have been a lunar observing guy for many years.
    Thanks Andy for the angular comparison ; I was wondering about that ....and also how much closer in miles is this lunar perigee than the usual or average perigees. ?? I was also trying to figure if the increased brightness was significant enough to be apparent...That's a lot harder to recognize on a distributed source....at least for me.....My cognition doesn't always remember on intensity levels.... ;))

    Ok; just found this chart; looks like for 2016 the difference from closest to fartherest perigee is about -13,000 Km. (est. from the chart)
    However, this month's perigee looks like it barely beat out that of last April. Hmm. So if this was the closest in 70 years ....it must have been by a v. small margin.

    Edit:
    Ok; here's the numbers he lists to compare Apr. with Nov, perigees for 2016 .
    Apr. - 357163 km
    Nov. - 356511 km
    OK...that shows a difference of only 652 Km. or 405 miles.

    Come on, it's just another 18 years later. I hope you can enjoy it, then.

    That is a quarter life expectancy on this world. While everyone wants to live forever pragmatism says that about 25% of everyone you are talking to here will not live to see the next super(full)moon.

    I agree, it is not a long time but in human terms it can amount to forever. I am glad to see those coming up after me looking forward, (there is much to see that is not now known).

    You guys scientists are always pragmatic :smile:. Saying that it's God who controls our lifes (or the weather or the orbit of the planets or even the location, superposition, of the electrons) would be useless :smile:.
    Okay, what I want to know is this.
    I'm no science guy.
    So this supermoon, it's because the moon looks very large doesn't it? So it's always be at full moon?
    Will the moon is in apogee (or perigee) in full moon or new moon?
    Or full moon doesn't have to do the the moon in apogee?
    Or supermoon should always be at full moon?

    Second, perhaps this is off topic.
    I've read the inclination angle of earth and moon, but still doesn't understand.
    Can we draw the orbit of moon and earth around the sun on a sheet of paper?
    I mean the orbit of the moon is exactly on the earth orbit plane around the sun?

    Thanks

    In this image, yes it is. However, Take two quarters and put one 8 feet away and the other 9 feet away and you will have a good representation of how the moon appears to the naked eye at perigee and apogee. Now if these quarters are against a plain background, and far enough apart that you can't directly compare them side by side, you would be hard pressed to notice the difference in their apparent size.

    no it's not, else we would get a total eclipse of the sun and moon every month

    have a think about it :wink:

    Not really, if somehow the distance prevents it?Okay...
    Now, about supermoon. Supermoon doesn't always have to be in apogee? But it has to be full moon?
