The nine planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. Moons, asteroids, comets, and meteoroids are also part of our solar system.

Why do planets have different characteristics?

Planets have different properties because they are different distances away from the sun, are different sizes, and are made up of different stuff from the earth. Very tiny planets do not have enough gravitational field to keep much of an atmosphere in.

What are the characteristics of the four outer planets?

The four outer planets—Jupiter, Saturn, Uranus, and Neptune—are all gas giants made primarily of hydrogen and helium. They have thick gaseous outer layers and liquid interiors. All of the outer planets have numerous moons, as well as planetary rings made of dust and other particles.

What common characteristics do all planets share?

Besides all of them being planets, all follow an elliptical orbit, all are spherical, and all are made of iron and nickel to some degree.

What are the 8 planets for kids?

Why 8 is a unique planet?

The earth is a unique solar system planet because, Conditions favorable to supporting life are only to be found on earth. The earth is neither too hot nor too cold. There are water and air in it, which are very important for our survival.

What are the main characteristics of our solar system?

Our solar system consists of our star, the Sun, and everything bound to it by gravity – the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf planets such as Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids.

What are 4 characteristics of the planet Jupiter?

Jupiter is the largest planet in our solar system and has a low density, rotates quickly, and has a cloudy-looking atmosphere. Jupiter’s diameter is 88,815 miles which are eleven times larger than the diameter of Earth.

Which planet is the hottest?

Venus’ thick atmosphere traps heat creating a runaway greenhouse effect – making it the hottest planet in our solar system with surface temperatures hot enough to melt lead. The greenhouse effect makes Venus roughly 700°F (390°C) hotter than it would be without a greenhouse effect.

How many types of planets are there?

Our solar system contains three types of planets: rocky, terrestrial worlds (Mercury, Venus, Earth, and Mars); gas giants (Jupiter and Saturn); and ice giants (Uranus and Neptune).

What are 5 characteristics of the inner planets?

All of the inner planets are solid, dense, rocky planets. The inner planets either do not have moons or have just one (Earth) or two (Mars). None of the inner planets have rings. Compared to the outer planets, the inner planets have shorter orbits around the Sun, but all the inner planets spin more slowly.
