what materials formed the solar system?
387234
Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a solar nebula—a spinning, swirling disk of material.

The inner planets of our solar system, Mercury, Venus, Earth, and Mars, originated from small dust and larger particles in the solar nebula that collided with each other over millions of years forming larger and larger particles (Figure 1a). These eventually became protoplanets.

The Sun is a huge, glowing sphere of hot gas. Most of this gas is hydrogen (about 70%) and helium (about 28%). Carbon, nitrogen and oxygen make up 1.5% and the other 0.5% is made up of small amounts of many other elements such as neon, iron, silicon, magnesium and sulfur.

The temperature of the early solar system explains why the inner planets are rocky and the outer ones are gaseous. As the gases coalesced to form a protosun, the temperature in the solar system rose. ... There were relatively few elements of any other kind in a solid state to form the inner planets.

Our solar system includes the sun and eight planets that orbit around the sun. The smaller, inner planets include Mercury, Venus, Earth, and Mars. The inner planets are rocky and have diameters of less than 13,000 kilometers. The outer planets include Jupiter, Saturn, Uranus, and Neptune.

The solar system is host to two broad categories of planets. The four closest to the sun — Mercury, Venus, Earth and Mars — are the terrestrial planets. They have rocky surfaces enclosed by relatively shallow atmospheres. The gas and ice giants — Jupiter, Saturn, Uranus and Neptune — are outliers.

Jupiter and the sun are both very similar in their overall composition, as they are both made up almost entirely of hydrogen and helium. The sun has a core that is so hot that it causes hydrogen to separate into individual electrons and protons; Jupiter's core is made of liquid metallic hydrogen.

Answer 1: Pluto is NEITHER. Terrestrial planets are made up (mostly) of metal (iron) and rocks (silicates). Jovian planets are giant gas balls not unlike the SUN although they have a small rocky central core.

The terrestrial planets are made of land and water etc. And the Jovian planets are made almost entirely of gas. ... Between the two planets of Mars and Jupiter lies something referred to as the "Asteroid Belt" which is basically what separates the two types of planets in the solar system.

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. ... In our solar system, the four "gas giants" are Jupiter, Saturn, Neptune, and Uranus.

Our solar system is made up of a star—the Sun—eight planets, 146 moons, a bunch of comets, asteroids and space rocks, ice, and several dwarf planets, such as Pluto. The eight planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

Terrestrial and Jovian Planets They are rocky with a dense metal core consisting mostly of iron. Planetary scientists theorize that Mars and Venus may once have had conditions like Earth's, favorable to life.

Mercury, Venus, Earth, and Mars are the planets closest to the Sun. They are called the inner planets. The inner planets are made up mostly of rock. The outer planets are Jupiter, Saturn, Uranus, and Neptune.

Meteorites have traditionally been divided into three broad categories: stony meteorites that are rocks, mainly composed of silicate minerals; iron meteorites that are largely composed of metallic iron-nickel; and stony-iron meteorites that contain large amounts of both metallic and rocky material.

Our Solar System consists of our star, the Sun, and its orbiting planets (including Earth), along with numerous moons, asteroids, comet material, rocks, and dust. Our Sun is just one star among the hundreds of billions of stars in our Milky Way Galaxy. ... The universe is all of the galaxies – billions of them!

Corresponding, to this theory, planets what we call know were formed within the disk. Whereas, in protoplanet Hypothesis we get to know the present solar system and universe working. Though having many things in common with nebular hypothesis this hypothesis has modern implement of states of matter and fluid.
