Is there a date and or time when all of Earths landmass has the sun up?

…Excluding tiny Pacific atolls?
The pacific cover a little less than half of the planet, so, there must be someday, when there is light outside, all over the worlds land?

Have you been looking at maps without New Zealand?

We are the antipodes - on the absolute other side of the globe from Europe. Unless you count reflected moonlight, we cannot see the sun when Europeans do. And (I might add) it’s basically the same for our Australian cousins (may they fumble the ball and knock on).

Stop looking at flat projections and look at a globe with a torch.

Not to mention that huge continent around the South Pole - Antartica.

It’s impossible, the planet is a ball.

Maybe the OP is a flat-earther? - “The Flat Earth Society’s Twitter feed currently boasts over 60,000 followers.” https://www.sciencefocus.com/the-human-body/the-rise-of-the-flat-earthers/

Flat maps work fine too, as long as you model daylight correctly. OP should fiddle with this map, experimenting with different seasons and times of day to understand what parts of the earth are/aren’t illuminated at any given moment.

Since land masses aren’t evenly distributed, that’s irrelevant l.

Ha ha ha. Maybe lookup before you post sarcastic comments . :rolleyes:
Australia’s antipodes is the middle Atlantic Ocean. NZ north island is antipodean to central Spain, but the South Island is mostly in the Bay of Biscay.

The only large landmass antipodes is SE and East Asia and S America.

Yes, there is such a time. It was 175 million years ago.

Pangea?

It depend on your definition of “all over the worlds land”. Sunlight cannot completely cover every piece of land on the earth. The closest you can get is to have the Pacific in the dark, and then you have to choose between either North America or Australia (plus New Zealand) in the dark. There isn’t enough angle of rotation of the earth for both North American and Australia to be sunlit simultaneously.

Any other rotation of the earth will end up with even more land in the dark.

However, if you define “all over the worlds land” to mean that every continent has at least one part that is sunlit, and do not mandate that the entire continent has to be in sunlight, then it is possible. Again, with the Pacific being in the dark, you have a short time while the easternmost part of North America is in the sun while the westernmost part of Australia is also in the sun. Both continents are mostly in the dark, but there is a small part of each continent that is sunlit.

For those who do not have a globe handy, there is an online 3d globe here that you can play with to see exactly what I mean: 3D Interactive Earth Globes

For the record, this isn’t true. The area of the Pacific Ocean is about 162 million square kilometers, while the total surface area of the Earth is 510 million square kilometers. So the Pacific is 31% of the Earth’s area, which is a lot less than “a little less than half.”

Isn’t that sufficient to answer your question in the negative? A pair of anitpodal points can’t both be sunlit, except for a split second at sunrise/sunset.

Not sure if Coronas resulting from sun activity counts.

Coronal mass ejection events, also known as “the blobs” by astronomers, are a release of plasma from the sun. Read more here - Coronal mass ejection - Wikipedia

The earth is far away from the sun and most of “the blobs” don’t hit earth.

However, in 1859 one such blob did hit earth and caused “northern lights” to be visible on the equator and generally “lighted up” the earth :

If we get a hit in today’s times, I suspect there will be mass disruptions / damage to electrical / communications equipment. On the plus side, the night sky will be lighted up :slight_smile:

Logically, there has to be one second of one minute of one day each year in which the largest amount of landmass receives direct sunlight. Does anyone know when that is?

Which year?

Let’s start with 2019 and move on from there. Someone here has to know, right?

I’m not being argumentative, BTW - I’m genuinely curious.

What I am saying that it is not logical that it be the same second every year-the universe is not a Swiss timepiece. There are fluctuations throughout the system.

Not sure what you mean by direct sunlight. Unless the sun falls below the horizon in Antarctica then this should happen every day. I assume it happens at noon on a longitude through the Eurasion landmass.

I’ll wager it’s sometime close to the December solstice, since 100% of Antarctica is lit up. After that, it’d take a computer model to track the % of landmass illuminated at any time during a 24-hour cycle to find the moment of maximum illuminated land area. Absent that, I’ll wager it’s a time that lights up most of Africa, Asia, and Australia, something like this.

That’s what I imagined. But is the maximum land area of Antarctica illuminated on just one day of the year?

Right. Study this video showing the global projection of daylight and you’ll find it’s not possible for all the world’s landmass to be sunlit at the same time.
