    Globe Earth question: Percent of the Earth receiving sunlight at a given time

    And I did alot of clicking and dragging!

    Globe Earth question: Percent of the Earth receiving sunlight at a given time

    I did tilt the axis every which way, but It didn't make a difference. The answer seems to be that the 3D model doesn't show 50%, so it wouldn't matter. But it was still helpful to learn from you it should be pointed toward me to approximate solstise rather then may admittedly crude method of...

    Thanks for your input. Have a great night.

    Globe Earth question: Percent of the Earth receiving sunlight at a given time

    I believe I said you answered my question. I was hoping for a rough estimate on how much the 3D model does show , but I can see physics guys don't deal in rough estimates. Many thanks for everyone here. Have a great night. My goal now is to enjoy the rest of the night.

    Globe Earth question: Percent of the Earth receiving sunlight at a given time

    I don't have any questions about the 99% claim. The article explained it really well. I cannot set the date on the 3D model.

    Globe Earth question: Percent of the Earth receiving sunlight at a given time

    Thanks someone seems to have answered my question. The 3D globe is in the link. The other link is to an article, which is July 8. I cannot pick the day on the globe. I was trying to see if I could align it to roughly the solstice.

    Globe Earth question: Percent of the Earth receiving sunlight at a given time

    Way over my head, but interesting! Thanks. It does answer my question on why I could not make the map align with the model. I was really perplexed. And one more thing, could you give a rough estimate looking at the link of the 3D map, of how much % you think is showing? Just so I have an idea...

    Globe Earth question: Percent of the Earth receiving sunlight at a given time

    Thanks someone else mentioned infinity. I don't understand this. The Sun is not at infinity, and illuminates 50% of the Earth. So how can we not see this? Thanks for your reply.

    Globe Earth question: Percent of the Earth receiving sunlight at a given time

    1. Thats my question! So you are saying the 3D Globe is not going to show 50%. Any idea how much it does show? Isn't there a math formula for the distance needed to show 50% from the diameter? Btw, my Globe link is the same as yours only selected for terrain. 2. I have zero confusion over...

    Globe Earth question: Percent of the Earth receiving sunlight at a given time

    You do raise an good point though. Follow up question. What would be the distance that a 50% view of the Earth would be achieved? Math equation?

    Globe Earth question: Percent of the Earth receiving sunlight at a given time

    Hmmm, thats interesting. I have looked at several 3D models with the same result. Do you have one where it does show 50%? Seems to me that would be a pretty basic standard. And how would it need to be at infinity? The Sun is not at infinity. Thanks for your reply.

    Globe Earth question: Percent of the Earth receiving sunlight at a given time

    Hopefully, this illustrates the problem. Here is a screengrab from 3D earth. This is one of my attempts to get alignment Notice how it does not align with the 50% daylight region? There are many discrepancies: It should extend nearly to Antarctica. It should include more of South America It...

    Globe Earth question: Percent of the Earth receiving sunlight at a given time

    Yes, its a good article. To be clear, Im not confused about the twilight region. I specified the daylight region. Try to line up the visible daylight region from the first link, with a global 3D map. It just doesn't align.

    Globe Earth question: Percent of the Earth receiving sunlight at a given time

    Yes, I read it. Its not my question. My question is why the 50% of the daylight region does not align with what is visible on a 3D Globe. I have tried for hours, and it doesn't fit the parameters. If you can do it, all it takes is a screenshot to show it.

    Globe Earth question: Percent of the Earth receiving sunlight at a given time

    I recently stumbled on a problem I can't solve. For background, there is a recent story from July 8 about 99% of people receiving sunlight at 11:15 am. Anyone can google it and it's explained fairly well at time and date. There is an illustration. Here...
