From rocks, ice, dust, and gas. This process is called Accretion.
hey
They are all beyond the asteroid belt. They all have a %composition of ice due to the distance they formed from the sun. Planets inside the asteroid belt have no ice composing their structure (the planet itself is not made of ice) as it was too warm when they formed. If we neglect Pluto they have a lot of things in common, however Pluto and Charon are keiper belt objects and are very dissimilar to the gas giants
Ice formed it.
Planets are not rings, of anything.
Ice froze and they were formed...
Although there are speculations of ice caps on several moons and planets outside of the solar system, the only confirmed planets within our solar system to possess them are Earth and Mars.
There are a few planets which have ice. Earth has ice. Mars is believed to contain ice far underneath its surface. Pluto which is no longer classified as a planet has a surface which is completely frozen.
The planets formed out of the solar nebular there is no concept of the "first" they all formed slowly at the same time.
Because the nebula has gas and rock/ice/dirt so each planet formed using gas and rock/ice/dirt.
Because the nebula has gas and rock/ice/dirt so each planet formed using gas and rock/ice/dirt.
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.
