SOLAR SYSTEM

Detailed explanation-1: -If a planet is close to the Sun, the distance it orbits around the Sun is fairly short. This distance is called an orbital path. The closer a planet travels to the Sun, the more the Sun’s gravity can pull on the planet. The stronger the pull of the Sun’s gravity, the faster the planet orbits.

Detailed explanation-2: -Yes. The speed at which a planet orbits the Sun changes depending upon how far it is from the Sun. When a planet is closer to the Sun the Sun’s gravitational pull is stronger, so the planet moves faster.

Detailed explanation-3: -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.

Detailed explanation-4: -Compared to the outer planets, the inner planets are small. They have shorter orbits around the Sun and they spin more slowly. Venus spins backward and spins the slowest of all the planets.

Detailed explanation-5: -Save this answer. Show activity on this post. As far as our understanding of planetary formation goes, rocky planets tended to form closer to the Sun because the materials they’re made of–silicates and heavier gases–‘fall’ inwards towards the Sun.
