Detailed explanation-2: -“The formation of the planets in the outer solar system started later, but also finished more quickly; the inner planets needed a lot longer, ‘’ Lichtenberg says.

Detailed explanation-3: -Among the planets, Jupiter likely formed first, perhaps as soon as a million years into the solar system’s life, scientists have argued (opens in new tab). Scientists have developed three different models to explain how planets in and out of the solar system may have formed.

Detailed explanation-4: -Space Environment Earth and the other three inner planets of our solar system (Mercury, Venus and Mars) are made of rock, containing common minerals like feldspars and metals like magnesium and aluminum. So is Pluto. The other planets are not solid.
