What are the 4 inner planets composed of?

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. Jupiter, for instance, is made up mostly of trapped helium, hydrogen, and water.

Which is not inner planet?

Venus. The correct answer is option (b). Explanation: The first four planets, that is, Mercury, Venus, Earth and Mars, are close to the Sun.

What is inside Planet?

The Earth’s interior is composed of four layers, three solid and one liquid—not magma but molten metal, nearly as hot as the surface of the sun. The deepest layer is a solid iron ball, about 1,500 miles (2,400 kilometers) in diameter. Although this inner core is white hot, the pressure is so high the iron cannot melt.

What do all of the inner planets have in common?

The four inner planets — Mercury, Venus, Earth and Mars — share several features in common. Astronomers call them the “terrestrial planets” because they have solid, rocky surfaces roughly similar to desert and mountainous areas on the earth.

What divides the planets into inner planets and outer planets?

The Asteroid Belt is the line that separates the inner and outer solar system. Planets ‘inside’ the Asteroid Belt are known as ‘Terrestrial’ planets – they are rocky worlds with a metallic core; they are also small.

What are inner planets and what are their names?

The Inner Planets of Our Solar System Mercury: Of the inner planets, Mercury is the closest to our Sun and the smallest of the terrestrial planets. Venus: Venus, which is about the same size as Earth, has a thick toxic atmosphere that traps heat, making it the hottest planet in the Solar System. Earth: Earth is the third inner planet and the one we know best.

What distinguishes the inner and outer planets?

The inner planets are closer to the Sun and are smaller and rockier. The outer planets are further away, larger and made up mostly of gas. The inner planets (in order of distance from the sun, closest to furthest) are Mercury, Venus, Earth and Mars. After an asteroid belt comes the outer planets, Jupiter, Saturn, Uranus and Neptune.
