No, not all planets have seasons. Earth experiences seasons due to its axial tilt. Planets like Venus and Uranus also have seasons, while those like Mercury and Jupiter have minimal seasonal variations. Other planets, like Mars, have seasons but they can be different from those on Earth.
Earth and Venus. From Earth Venus and Mercury are planets visible as "morning" and "evening" stars. From Venus, Mercury would appear in the morning and evening sky. From Mars I would expect Earth, Venus, and Mercury to all be morning and evening "stars."
37.5% not including PlutoFirst Answer:50% including Pluto.Second Answer:Of the eight planets in our solar system, three are smaller than earth. 3/8 = 38%.However, we also know (to date) of more than a thousand other planets, orbiting distant stars. None of these planets so far is smaller than earth, but that it because planets as tiny as ours are difficult to detect. We expect probably half of all planets would be our size or smaller.
The Earth would not have seasons if its axis was not tilted with respect to its orbit around the Sun. Seasons are caused by this tilt, which affects the angle at which sunlight reaches different parts of the Earth throughout the year.
In that case, there would be hardly any seasons. There would still be slight variations in yearly temperatures, as a result of the fact that Earth is sometimes closer to the Sun.

There would be no four seasons if the earths axis was not tilted.
If Earth's axis were not tilted, there would be no seasons as we know them. The tilt of Earth's axis is what causes different parts of the planet to receive more direct sunlight at different times of the year, creating the four seasons. Without this tilt, the amount of sunlight reaching each area of the Earth would remain constant throughout the year, leading to a more consistent climate globally.
There would be no seasons on Earth if the Earth's axis had no tilt because throughout the year the Earth would get an equal amount of sun everywhere.
Earth and Venus DO follow elliptical orbits around the sun (though the orbit of Venus is only very slightly elliptical). Earth's orbit being elliptical is, combined with our axial tilt, why we have seasons.
Its most likely that they do. Any planet with an axial tilt will have seasons throughout its orbit. Eclipses of orbiting moons are also likely to occur on these exoplanets, though it would be rare to find an orbiting moon that is almost the same apparent size as the star - as with Earth.
In that case, the seasons would be more pronounced.
If the Earth's axis were not tilted relative to the plane of the ecliptic, we would not have any "seasons" at all.
Earth and Venus. From Earth Venus and Mercury are planets visible as "morning" and "evening" stars. From Venus, Mercury would appear in the morning and evening sky. From Mars I would expect Earth, Venus, and Mercury to all be morning and evening "stars."
It would more correct to say that the Earth has seasons because it tilts, rather than saying the Earth tilts to make seasons.
There would be no seasons.
the seasons will change!!
