Question

Planets, stars, and galaxies are composed of different forms of matter which material makes up the planets in Earth's solar system?

Answer 1

The planets in Earth's solar system are composed of matter that originally formed from a massive cloud of gas and dust. The inner terrestrial planets have metal-rich, rocky compositions, whereas the outer gas giants are mostly hydrogen and helium.

Step-by-step explanation:

Planets in Earth's solar system are composed of various forms of matter that condensed from an enormous cloud of gas and dust about 4.5 billion years ago alongside the formation of the Sun. Composition differences arise from the location where these objects formed. The inner planets, known as terrestrial planets, have a metal-rich composition, comprising predominantly rocky materials.

In contrast, the outer gas giant planets—Jupiter and Saturn—are composed mainly of hydrogen and helium, reflecting the primordial matter from which the solar system originated. Other objects, such as icy comets in the Oort cloud and Kuiper belt or rocky and carbon-rich asteroids, show the diversity of materials present in the solar system.

Answer 2

they all have solid cores of rock, metal, and maybe even ice, but these planets are totally enveloped in thick atmospheres of gas. Hydrogen and helium (the two lightest elements) make up most of the gases in the atmospheres of these planets
