In all probability, all the planets are about the same age. They formed around the same time as all of the other planets give or take a few million years.
no
all planets.
No, other planets are rotating at other speeds.
No
i believe that the seasons are not exactly of the same length. because a year has 365 days. 365 is not even and is not divisible by 4. therefore it can never be of same length. if they are of the same length somehow, the seasons must have shifted to some other time of year as years go by.
At the same time that the Earth (and the other planets) formed : 4.5 billion years ago.
Certainly yes, it meteorite impact formed the same as sites on the other planets.
No. Athens is a city in Greece. Planets are other worlds.
The age of Venus is about 4.5 billion years old, the same age as the other planets and the sun. This is because scientists estimate the big bang about 4.5 billion years ago.
No two planets in our solar system have the same length of day or length of year. Compared with Earth, these planets have longer years: Mars, Jupiter, Saturn, Uranus, Neptune. These have much longer days than Earth: Mercury and Venus. Mars has a day that's slightly longer than Earth's day. Depending on the particular definition of "day" that is used, two planets have a day that's longer than than that planet's year. They are Mercury (solar day) and Venus (sidereal day).
Other than length they appear to be the same.
