Earth has four seasons, but do other planets in our solar system also have hot summer days and cold winter nights?

Every year, Earth follows a familiar pattern of seasonal changes: As summer rolls around in the Northern Hemisphere, winter creeps in in the Southern Hemisphere, and vice versa.

But do other planets have seasonal patterns, too?

Indeed, other planets, dwarf planets and moons in our solar system do have seasonal cycles — and they can look wildly different from the ones we experience on Earth, experts told Live Science.

To understand how other planets have seasons, we can look at what drives seasonal changes on our planet. "The Earth has its four seasons because of the spin axis tilt," Gongjie Li, an astrophysicist at Georgia Tech, told Live Science. This means that our planet rotates at a slight angle of around 23.5 degrees.

So, when Earth is on one side of the sun, the Northern Hemisphere is pointed toward the sun and the Southern Hemisphere is facing away, explained Shane Byrne, a planetary science professor at the University of Arizona. When our planet moves to the other side of the sun six months later, the Northern Hemisphere faces away.

Mars has an axial tilt of around 25 degrees. Because this value is so close to Earth's tilt of 23.5 degrees, the amount of seasonal variation on Mars is similar to our planet's.

"Just like on the Earth, you have permanent darkness and permanent daylight at the polar areas, depending on whether you're in the winter or the summer; then you can flip between those two states every half a year," Byrne told Live Science. But interestingly, instead of water-based ice, winters on Mars are dominated by carbon dioxide ice (or dry ice), which can form spidery cracks on the surface on the planet.

In contrast, some planets in our solar system have massively different tilts, leading to more extreme changes throughout the year. For instance, Mercury has no tilt, so "there's almost no seasonal change at all," Byrne said. On the opposite end of the spectrum, Uranus has a 90-degree tilt, so the poles are either completely facing the sun, or not at all, meaning its seasons are intense: Summers are filled with long stretches of constant blazing sun, while winters plunge into perpetual chilling darkness.

But tilt isn't the only factor that drives seasonal changes.

The shape of a planet's orbit can also influence seasonal variations in weather, because planets' orbits tend to be ellipses, rather than perfect circles, so as a result, some planets are sometimes very far from the sun and very close to it at other times.

For example, Mercury has an "eccentric" orbit, which contributes to its seasonal variations, Li said. Pluto, too, has a very elliptical orbit that pushes its variations to an extreme, Byrne said.

These two factors — a planet's tilt and the shape of its orbit — can also change over time. Byrne, who studies climate records on Mars, explained that the tilt on the Red Planet wasn't always 25 degrees.

In fact, models, published in the journal Earth and Planetary Science Letters in 2018, have shown that Mars's tilt has varied from 10 to more than 40 degrees over the course of billions of years. This has led to extreme fluctuations in the planet's yearly cycle.

"So it's almost just random chance that it happens to be similar to the Earth today," Byrne said.

"On Earth, we're very lucky, this spin axis is quite stable," Li said. Due to this, we've had relatively stable seasonal cycles that have persisted for millennia, although the broader climate sometimes shifts as the entire orbit of Earth drifts further or closer from the sun.

Such stability has likely helped life as we know it develop here, Li said. Scientists like her are now studying planetary conditions and seasonal changes on exoplanets to see whether life could exist in faroff worlds. For now, it seems as though the mild seasonal changes and stable spin tilts on Earth are unique.

Wanna know something fun? Im so far down the rabbit hole im convinced “space” might not even be real. That NASA is a huge psyop to launder money. I think the moon footage is fake. I think the videos of astronauts are hollywood productions. And that we cannot leave the planet and pierce the “firmament”. Or as the simpsons did it, we are under a “dome”. And it separates the waters from above and below.

I think the concept of the universe being so vast could possibly be a way of psychological warfare to make us each feel insignificant. When in fact we are very powerful. It feels like “they” are constantly trying to kill us by poisoning our food, water, air, and calcification of our pineal glands.

There are no actual pictures of earth that are not cgi. All our internet and communications are run by vast cables running underneath the oceans between continents, then to cell towers, etc.

And picture of “space” never really shows all these thousands of satellites and space debris that supposedly exist.

Why is it that none of the powers to be on the planet can agree on anything, EXCEPT no one is allowed to goto Antarctica. Except with strict approval and regulations.

I think “aliens”are from the inner planet and oceans. I think there was many previous civilizations that existed on our planet previously. Like when lewis and clark went to explore the west of america in the Louisiana purchase. I think they came upon all these previously built architecture built by a previous more advanced civilization. I think they locked up anyone who remembered the old world in asylums. That all these world wars was to actually destroy all the evidence of the old world. All the old pictures seem to have been altered to white out the skies to not show all these air ships.

Tartarians were whom possibly built all these megaliths, and amazing buildings. I think cathedrals used to be places of healing through sound waves. Why did they confiscate all those bells to be repurposed into bullets for war. Taking something that was meant for healing, and turning it into something for destroying.

American history and education was bought out by a billionaire to and i quote “i dont want a nation of thinkers, i want a nation of workers”. Programming us to follow orders without question. School is a scam. I felt it in my heart and soul my entire childhood that school was evil.

I think hollywood is evil. The “devil” as some would call it. To be an A-list celebrity one must sell their soul, and commit heinous acts upon their fellow man. Usually children. Its all controlled by the same evil entity.usually always leads back to the same few familys OVER AND OVER in history. The Rothschilds, rockefellers, etc.

Not to be antisemitic. But their people were chased and banished from like 110 countries in history. The jewish would set up a central bank system, and eventually owned everything, then the king would kick them out of the country. And they would goto the next country and set up another central bank and manipulate by things like coin clipping and melting down the clippings to make new coins. Their homes would be searched and they would be filled would coin clippings. Why do they own everything too?? Blackrock, van gaurd, state street own everything! And fund all the wars….why dont i have any rich jewish friends??? Where yall at?? Im trying to kick it lol

The titanic wasnt actually sunk, it was insurance fraud. Another ship that was old was refinished to look new and painted with the name titanic. Jp morgan at the last minute along woth the rothschilds all departed the ship right before the maiden voyage. And all the wealthy people who were opposed to the creation of the federal bank were killed on that ship. And the federal reserve was created in the next year. JP morgan got a huge insurance payout for the “titanic”. And got all his ops killed off.

Anyways. So i dunno if we even a globe as a planet. Flat earth seems a little odd. Being surrounded by an ice wall with other lands on the other side of it, and our planet is bigger than we have been taught would be kinda cool. Bout that fringe.

TL;DR space might be fake. Katy perry is not an astronaut.
