SOLAR SYSTEM

Detailed explanation-1: -A planet farther from the Sun not only has a longer path than a closer planet, but it also travels slower, since the Sun’s gravitational pull on it is weaker. Therefore, the larger a planet’s orbit, the longer the planet takes to complete it.

Detailed explanation-2: -Neptune takes the longest time to go around the sun. Neptune orbits the Sun at an average distance of 4.5 billion km. Like all the planets in the Solar System. Neptune follows an elliptical path around the Sun.

Detailed explanation-3: -Conversely, a shift in the orbit moving Earth farther from the sun would cool and potentially freeze the planet. Oceans would be covered in ice, causing them to release less carbon dioxide and vapor.

Detailed explanation-4: -Aphelion is the point of the Earth’s orbit that is farthest away from the Sun.

Detailed explanation-5: -The third law expresses that the farther a planet is from the Sun, the slower its orbital speed, and vice versa. Isaac Newton showed in 1687 that relationships like Kepler’s would apply in the Solar System as a consequence of his own laws of motion and law of universal gravitation.
