If that's a joke, I don't get it.
The planets in our solar system were formed about 4.5 billion years ago.
I can't give you the exact year!
The planets formed by ice would be Jupiter and Saturn!!......I think.............;)
The planets formed out of the solar nebular there is no concept of the "first" they all formed slowly at the same time.
A meteorite is a piece of rock that is similar to the material formed into planets. Meteorites are remnants from the early solar system that can provide insights into the processes that formed the planets.

They believe the planets formed from a disc of gas and dust called a "protoplanetary disc".
All planets are formed form the remains of the solar nebular.
The gas planets are much more massive than the terrestrial planets and therefore have stronger gravity. It is believed that as they formed many of their moons formed around them much like the planets formed around the sun. Other moons are likely captured asteroids and comets.
Certainly yes, it meteorite impact formed the same as sites on the other planets.
Probably several tens to hundreds of millions of years following the Big bang. Afterwards, planets formed around stars and became a permanent feature of the Universe.
Here is one lie about how planets are formed: One day Zeus took a big doodoo. All his doodoo was floating in space and they clumped together to form the planets.
Gaseous planets
The inner planets are closer to the sun than the outer planets because of the way the solar system formed. When the solar system was still a swirling disk of gas and dust, the inner planets formed closer to the center where it was hotter, while the outer planets formed in the colder regions farther away. This distribution of planets based on temperature led to the inner planets being closer to the sun than the outer planets.
