Is the moon artificial? Why is the angular diameter seen from earth the same as the sun?

Sun: 31.6' - 32.7'
Moon: 29.3' - 34.1'

There are Universal laws. The shapes, sizes, and locations of planets subscribe to those laws.

The source of those laws... gets debated in 90% of the threads on GLP...

An eclipse as seen from earth is probably one of the rarest events in the entire cosmos. A perfect match. A moon exactally 400 times closer, and smaller than the planets star. The odds are quite literally astronomical.

It's just an interesting coincidence.

ha

Go back to bed

Heres another: Prince William born same day as a solar eclipse and his newly engaged gf Kate Middleton born same year on the day of a lunar eclipse.

Thinks thats strange my friend? look it gets even stranger:

I enjoyed the info about prince William

No they are different ... easily seen in a full solar eclipse.

any other moons in our solar system with similiar match ?
jupiter, saturn ?

hard to simulate, but i will try

They are the same within a margin of error. Where are you getting your information from?

Oh- you think there's some rhyme and reason to it? Some *cough* ..."intelligent design", perhaps? *cough*

Seriously. You think there's some actual "reason" for the angular diameter of the sun and moon being similar? Or, perhaps, you think the moon is "artifical"? (I'm curious as I type this if you even have ANY idea as to the leading theories how the moon was actually formed...But, because I'm guessing you don't spend a lot of time reading astronomy...you probably don't).

(but maybe you do- surprise me; I love astronomy and love talking astronomy)

Nonetheless, I'll be wide awake waiting for (a hopefully?) coherent response....

Cool.

I've read the theories on how the moon was created and I'm not saying it is artificial, but the truth is, even astronomers aren't certain where the moon came from and their theories are pretty wild too.

It is the most sensational, spectacular and glaringly obvious sign to inform an intelligent species that they are not alone in the universe.

If the geometry is perfect, why are some solar eclipses total (that is, the entire surface of the sun is blocked for a period of up to 7 minutes), and some are annular (that is, the moon's apparent size is not large enough to completely cover the sun, leaving a ring of light visible at the midpoint of the eclipse)?

The Moons distance is not a constant.
At apogee the moon is farther from Earth than it is at perigee.
This is when the lunar disc is at it's "smallest" as seen from Earth and it cannot entirely block the bright light, so eclipses which occur at, or reasonably close to apogee are not total, they are called annular.

Total eclipses occur when the moon is at it's mean distance from Earth which just happens to be 384,400 Km.

That's another 400 for you...

The Universe is an equation.
Mathematics exists independently of humanity.
It is the language of God.

O.o

Only joking, but it's still pretty spookeh.

its all in the book

From Wiki: [link to en.wikipedia.org]

"The Moon's distance from the Earth can vary by about 6% from its average value. Therefore, the Moon's apparent size varies with its distance from the Earth, and it is this effect that leads to the difference between total and annular eclipses. The distance of the Earth from the Sun also varies during the year, but this is a smaller effect. On average, the Moon appears to be slightly smaller than the Sun, so the majority (about 60%) of central eclipses are annular. It is only when the Moon is closer to the Earth than average (near its perigee) that a total eclipse occurs"

Its a small earth like planet caught in the gravitational pull of the massive size of earth in comparison. The atmosphere completely froze up thats what gives the whitish color. we couldn't see what was under the massive size of that ice that covers the small surface. The reflection of the sun light makes it bright to the human eye but you cant see through the large layer of ice...

Earth has perfect geometry correct? well think of the moon in correlation to it. also if you think space is some sort of liquid or energy, etc. well perfect spheres form like bubbles in space, just like gas giants and most other planets. life could have possibly flourished there when closer to earth. do I make any sense at all or am i just trippin? can an expert(GLP'er)help me out here? ...

Nah, you're just talking bollocks

There are four types of solar eclipses:
A total eclipse occurs when the dark silhouette of the Moon completely obscures the intensely bright disk of the Sun, allowing the much fainter solar corona to be visible. During any one eclipse, totality only occurs at best in a narrow track on the surface of the Earth.
An annular eclipse occurs when the Sun and Moon are exactly in line, but the apparent size of the Moon is smaller than that of the Sun. Hence the Sun appears as a very bright ring, or annulus, surrounding the outline of the Moon.
A hybrid eclipse (also called annular/total eclipse) shifts between a total and annular eclipse. At some points on the surface of the Earth it appears as a total eclipse, whereas at others it appears as annular. Hybrid eclipses are comparatively rare.
A partial eclipse occurs when the Sun and Moon are not exactly in line and the Moon only partially obscures the Sun. This phenomenon can usually be seen from a large part of the Earth outside of the track of an annular or total eclipse. However, some eclipses can only be seen as a partial eclipse, because the umbra passes above the Earth's polar regions and never intersects the Earth's surface.
The Sun's distance from the Earth is about 390 times the Moon's distance, and the Sun's diameter is about 400 times the Moon's diameter. Because these ratios are approximately the same, the Sun and the Moon as seen from Earth appear to be approximately the same size: about 0.5 degree of arc in angular measure.




The Moon's orbit around the Earth is an ellipse, as is the Earth's orbit around the Sun; the apparent sizes of the Sun and Moon therefore vary.[6][7] The magnitude of an eclipse is the ratio of the apparent size of the Moon to the apparent size of the Sun during an eclipse. An eclipse that occurs when the Moon is near its closest distance to the Earth (i.e., near its perigee) can be a total eclipse because the Moon will appear to be large enough to cover completely the Sun's bright disk, or photosphere; a total eclipse has a magnitude greater than 1. Conversely, an eclipse that occurs when the Moon is near its farthest distance from the Earth (i.e., near its apogee) can only be an annular eclipse because the Moon will appear to be slightly smaller than the Sun; the magnitude of an annular eclipse is less than 1. Slightly more solar eclipses are annular than total because, on average, the Moon lies too far from Earth to cover the Sun completely. A hybrid eclipse occurs when the magnitude of an eclipse changes during the event from smaller than one to larger than one—or vice versa—so the eclipse appears to be total at some locations on Earth and annular at other locations.[8]
Because the Earth's orbit around the Sun is also elliptical, the Earth's distance from the Sun similarly varies throughout the year. This affects the apparent sizes of the Sun and Moon in the same way, but not so much as the Moon's varying distance from the Earth. When the Earth approaches its farthest distance from the Sun in July, a total eclipse is somewhat more likely, whereas conditions favor an annular eclipse when the Earth approaches its closest distance to the Sun in January.

Yes,

the Moon is actually a huge spaceship.

It brought the human race to earth.

Any other questions?

Because the Moons distance from Earth is not a constant.

Haven't seen you in here for a while, nice to see you back.

The Moon is certainly hollow, and therefore must be an artificial object.

Whats the odds im wondering of a married couple, born in the same year both being born under an eclipse, a blue one for the boy and a pink one for the girl? Solar and lunar. Can any online mathimatician please tell me?

Ill try 4 eclipse p anum - 2 solar 2 lunar = 90*90= 1 in 8100.

doesn't mean it's artificial ... maybe it was just moved into it's current orbit

ur on the rite trak, kinda. there was life on the moon b4, just google 200,000year old statue found on moon. but the reason for life on that rock is not bcuz it was closer to earth but becuz earths atnasphere was very different 150,000 years ago, the thermosphere stretched much fertheer into space and the moons gravuty cought itself sum greenhouse gas and stabalized the atmosphere. (the moon used to have day and night)

oh, and the earth is not a perfect cercle but slightly pear shaped, and the two spheres r spheres cuz bubles r round.

i wouldnt call space liquide energy, but empty space has sum form of energy, if it ddnt it would slip into a different demension.
