Accretion because usually they form from a protoplanetary accretion disk.
The planets were not invented. They formed naturally around four billion years ago.
They believe the planets formed from a disc of gas and dust called a "protoplanetary disc".
The planets that were formed by light gases are called terrestrial planets, also known as the gas giants.The gas giants are:JUPITERSATURNURANUSNEPTUNE
The planets in the solar system are formed by fragment of the original cloud.
Gas planets are the planets formed with gas - eg earth has a crust so it is a rock planet. But Jupiter is a planet composed of gas so it is a gas planet. Nothing solid at all. The Gas Planets are: Jupiter Saturn Uranus Neptune

From rocks, ice, dust, and gas. This process is called Accretion.
The planets formed by ice would be Jupiter and Saturn!!......I think.............;)
The planets in the solar system are formed by fragment of the original cloud.
The disk of dust and gas that formed the Sun and planets is known as the solar nebula.The dense concentration of gas at the center of this rotating disk eventually became the Sun.
The planets of our solar system were formed at different times, the earth is known to have formed as a planet about 4.6 billion years ago but other planets in the solar system may have formed earlier or later as they were quite conceivably not formed in the same manner as the earth

All planets are formed form the remains of the solar nebular.
The planets formed out of the solar nebular there is no concept of the "first" they all formed slowly at the same time.
