Super moon Monday 11/14/16 . Full moon's closest approach in 70 years.
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.hagar said:At my age I probably won't be around then.

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.Andy Resnick said:Not true, the angular size difference is quite apparent:

Come on, it's just another 18 years later. I hope you can enjoy it, then.hagar said:At my age I probably won't be around 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.Stephanus said:Come on, it's just another 18 years later. I hope you can enjoy it, then.

You guys scientists are always pragmatic . 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 .hagar said: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).
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.Andy Resnick said:Not true, the angular size difference is quite apparent:
Stephanus said: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
Not really, if somehow the distance prevents it?Okay...davenn said:no it's not, else we would get a total eclipse of the sun and moon every month
have a think about it
Stephanus said:Not really, if somehow the distance prevents it?Okay...
Stephanus said:Now, about supermoon. Supermoon doesn't always have to be in apogee? But it has to be full moon?
Oh, okay.davenn said:but using existing real world distances that there currently are, the moon would always pass directly between the Earth and the sun
is it wasn't a total eclipse, it would be at least an annular eclipse. And because of the moon's closeness to the earth,
I'm pretty sure it would always be a total lunar eclipse
Stephanus said:Fullmoon always in either apogee or perigee?
And newmoon likewise?
Oh, I didn't know if it is such a coincidence.davenn said:no
full moon ALWAYS apogee
new moon ALWAYS perigee
davenn said:no
full moon ALWAYS apogee
new moon ALWAYS perigee
No, you didn't. It's easy to confuse them. (perigee and apogee)Jonathan Scott said:What are you on about? Have I missed something? This is definitely not generally true.davenn said:no
full moon ALWAYS apogee
new moon ALWAYS perigee
Super moon occurs when full moon is near to perigee (closest point of moon's orbit to earth).
Thank you very much JS. I think supermoon always in perigee, but it's not.Jonathan Scott said:Full moon and new moon occur at points in moon's orbit when it is away from the sun and towards the sun with respect to earth. This is independent of the apogee and perigee of the moon's slightly elliptical orbit around the earth. The orientation of the orbital ellipse is approximately fixed relative to the stars, so full moons (which occur about 13 times a year) occur at various different points in the orbit. The distances to those points vary approximately sinusoidally during the year, so about three or four consecutive full moons are near perigee (making super moons), three or four are near apogee (making the moon smaller than average) and the rest are somewhere in the middle.
The exact height of the perigee changes slightly due to other factors (depending for example on where Earth is in its own elliptical orbit) and the closest full moon in a given year may occur some time before or after the perigee. The recent super moon was a case where the perigee was at its closest for many years and the full moon occurred within hours of the perigee, so it was a "best case", but this is not very different from a typical super moon.

A Supermoon is a full moon that appears larger and brighter than a regular full moon. This occurs when the moon's orbit brings it closest to Earth, making it appear bigger in the sky.
A Supermoon occurs about once every 14 months. However, the distance between the moon and Earth varies, so the degree of "super" can also vary.
The Supermoon on Monday, November 14, 2016 is considered special because it will be the closest approach of the moon to Earth in 70 years. This means it will appear larger and brighter than any other Supermoon in recent history.
The Supermoon is caused by the moon's elliptical orbit around Earth. When the moon is at its closest point to Earth (perigee), it appears larger and brighter in the sky.
No, the Supermoon will not have any significant effects on Earth or our daily lives. While it may cause slightly higher tides, the difference will not be noticeable. The Supermoon is simply a beautiful and rare astronomical event to observe.
