SOLAR SYSTEM

Detailed explanation-1: -A planet’s orbital speed changes, depending on how far it is from the Sun. The closer a planet is to the Sun, the stronger the Sun’s gravitational pull on it, and the faster the planet moves. The farther it is from the Sun, the weaker the Sun’s gravitational pull, and the slower it moves in its orbit.

Detailed explanation-2: -On July 4, 2011, when the Earth was farthest from the Sun (aphelion, 152.1 million kilometers) it was traveling at 29.3 km/s.

Detailed explanation-3: -And the answer: Venus. As the second planet from the sun, Venus completes one rotation every 243 Earth days. In other words, one day on Venus equals 243 days on Earth.

Detailed explanation-4: -Venus, which is floating higher each evening in twilight, low in the west, is the slowest-spinning body in the known universe.

Detailed explanation-5: -The closer a planet is to the Sun, the faster it travels. Since Mercury is the fastest planet and has the shortest distance to travel around the Sun, it has the shortest year of all the planets in our solar system – 88 days.
