MissusMack08 the moons orbit and earth rotation are the same direction. The earth rotates faster than the moon orbits giving the appearance of them being opposite. Also I think you are assuming that any other object that would impede the sun would be in orbit around the earth. My 2 assumptions do not consider that. As the object would have to be similar in size and proportion to that of the moon (if orbiting Earth). My assumption is that if an object/planet were to block the sun it would be coming from the outer solar system, other side of the sun or somewhere not in ecliptic

My assumption is that if an object/planet were to block the sun it would be coming from the outer solar system, other side of the sun or somewhere not in ecliptic Ok, my bad. I could've swore that was what someone somewhere explaining the eclipse had said as to why the eclipse with the sun/moon was only 7 minutes and that if the moon was going the same direction with the earth, the eclipse would last a lot longer. But really it's because the earth spins so rapidly... one of the theories about Planet X (Gill Broussard's planet 7x) is that if the earth goes through the plasma stream trailing behind the incoming planet, it would severly slow down or even stop earth's rotation. That could also explain an extended eclipse with that planet. I don't know if the incoming planet would have to be in orbit around the earth, I was just thinking it would go slower if it moved between earth and sun in the same direction as earth spins, like two cars passing on the highway only going 1 mph difference, but you proved that wrong with the moon's already prograde motion (I looked it up 😉). |

WHOA! Prograde motion, so techy MissusMack08 A plasma stream slowing the rotation. That's outta my pay grade. I would think it may be possible, but the impact on the planet would be immediately catastrophic. If the earth slowed at all from the 1,000mph rotation, imagine what the oceans would do. EDIT - meant 1000 mph but i see its 792, which now doesnt make sense to me if the moon travels at about 2300mph |

One might also consider the make up of said "planet X/Nibiru". If it doesn't reflect much light, detection will be hard for us common folk and easier for the powers in high places to "hide" it.

My husband (the computer software developer/mathematician) explained it to me. If the moon was a fixed object in the earth's sky at some point on the earth (like, say over the US, the moon was straight up overhead and never moved) this would mean its angular momentum was the same as the earth's, but its actual momentum through space would be much faster than the surface of the earth's rotation because it has a larger distance to cover. So even though the moon is not a fixed object from our perspective, it is still orbiting at a much faster speed than the surface of the earth is rotating. |

MissusMack08 I'm confused by this...if the moon "rises" in the east, but the earth rotates west to east and the moon orbits west to east, how is it we "catch" the moon every day? It would seem the earth spins faster than the moon orbits. Is it due to the distance away from earth? Can you ask the geek mathematician please

Ok, the way the moon currently makes solar eclipses is by whizzing by in the opposite direction. This means it is only very temporarily in the way of the sun. If the moon, or any other object, went the opposite direction around the earth, then it could easily make a much longer duration eclipse. This is the difference between two cars travelling on a highway.
If two cars are travelling at 50 mph in the opposite direction, then when they meet, they are only "beside each other" for a very split second.
But if two cars are travelling the same direction, the first one at 50 mph, and the second at 51 mph, and the second car passes the first car, then the two cars are "beside each other" for a much longer period of time.

Maybe this helps if you have a smartphone or tablet at hand.
Install the free app Solar System Scope and you can check all rotations and orbits in question for yourself.

It would seem the earth spins faster than the moon orbits. Is it due to the distance away from earth? Can you ask the geek mathematician please Because the moon's angular velocity (I said angular momentum earlier, my bad- the velocity that an object changes degrees in a circle) is SLOWER than the earth's angular velocity (how fast an object on the surface changes degrees in a circle). But because the moon is so far away the actual distance through space it must travel to cover those degrees in the circle means the moon travels much faster (mph) through space than the earth's surface rotates. That's why it appears that the moon rises from the east. The earth and moon are traveling in the same direction but the earth is turning in degrees faster than the moon is along its orbit. ¿Me comprendes? |

No spreche de Deutsch! LOL Parts of this thread took me back about 35 years to my college physics class, which I withdrew from after the first session. It made my head hurt! |

I "get it"...gonna chalk it up to distance. Moon is faster but slower cuz it's far away. I'm stickin wit dat! 😁

Maybe if it was gradual, it wouldn't be so bad? |
