This stability allows us to have four very distinct seasons, with less sunlight reaching the Earth causing the coldness of wintertime, and more sunlight bringing the hot summer weather. Because the Moon is so large, its force or pull keeps the Earth optimally positioned at all times on its axis, and if the Moon disappeared, the Earth would wobble as it rotated around the Sun. If it were, then it is quite possible that the planet would wobble as it rotated around its own sun.
This would mean that portions of the planet would constantly be shifting toward and away from the sun without any warning to its inhabitants, leading to the extreme seasonal variation.
The same might not be true of Westeros, and it could be that the orbit that the planet makes around its sun is a very long elliptical shape. In this scenario, during its aphelion point furthest from sun the planet would be extremely cold, while at the perihelion point nearest the sun the planet would have a long period of summer. While this theory makes sense for describing the length of the seasons on Westeros, it does not explain why no one ever knows when the next season will arrive. Even with a very elongated orbit, the people of Westeros would have been able to observe a noticeable pattern over time.
The fact that everyone is taken by surprise when the seasons change makes it unlikely that an elongated orbit alone would be the cause of the phenomenon. Complicated Milankovitch Cycle. While our seasons here on Earth change four times per year, the planet is also undergoing climactic changes which occur on a much longer, yet still predictable cycle that astronomers refer to as the Milankovitch Cycle.
According to one intriguing theory the Game of Thrones world may have a much shorter Milankovitch cycles therefore resulting in a more irregular and complex climactic patterns.

According to Griffith, volcanic eruptions of that magnitude would cause several climate irregularities, such as mini-winters and years without spring. Thomas Douglas, an environmental chemist, agreed with Griffith's theory but also posits that asteroids and comets help cause the long winters.
Since asteroids leave a lot of dust in the atmosphere when they fall to Earth, the dust leads to a cooling effect that lasts for multiple years. Douglas also proposed that the tilting of Westeros' planet's axis is more extreme than that of Earth's, which causes the seasons to be more extreme. Whether the seasons in Game of Thrones are scientific or fantastical, they are important thematically to the story.
Summer usually signifies a time of peace, but once the series' many wars and conflicts begin to take shape, the threat of winter begins to loom. This is only made worse by the encroaching threat of the White Walkers. By the time Winter does come, the story is at its darkest point and the era of peace has long passed.
