None of them take exactly 200 years to orbit the sun. Here are the times it takes for our solar system's planets to orbit the sun once, in the order of closest to the sun to furthest away:
- Mercury: 88 Earth days.
- Venus: 224.65 Earth days.
- Earth: 365.24 Earth days.
- Mars: 687 Earth days.
- Jupiter: 11.86 Earth years.
- Saturn: 29.5 Earth years.
- Uranus: 84 Earth years.
- Neptune: 164.79 Earth years.
(- Pluto: 248 Earth years.)
Note: Pluto is no longer classified as a planet.
The reason I have used "Earth days" or "Earth years" is because a year on one planet is different to that on another. A year on a planet is the length of time is takes for the planet to revolve once around the Sun. So a year on Mercury is only about 3 Earth months, and a year on Pluto is about 2 and a half Earth centuries!
Also, a day is different on each planet too. A day on a planet is the length of time it takes for the planet to rotate once on its own axis. On Earth, this is about 24 hours. Pluto takes 6.39 Earth days to rotate once, so a day on Pluto (one period of light, one period of darkness in one specific spot) is about one Earth week!
Venus rotates very very slowly. In fact, it rotates so slowly, that it orbits the Sun once before it rotates once on its own axis. Yup that's right - amazingly, Venus's days are longer than its years!
Venus:
One rotation (day) - 243 earth days
One orbit (year) - 224.7 earth days
Well, I'm sorry I haven't answered your question, but Neptune is the one that takes the closest to 200 years to orbit the Sun. But, if you are looking for one that takes more than 200 years to orbit the Sun, then that would be Pluto. Although, seeing as Pluto is not a planet any more, and you are looking for a planet - it looks like the answer you are looking for is Neptune.
248 earth years to orbit the sun
365 1/4 days. Resulting in a leap year every fourth year.
The only planet in that category is the Earth, the planet most people live on. How does the orbit affect life? without the orbit there is no life on Earth, so it's fundamental really. The orbit keeps our temperature within narrow band so that life can exist and flourish. Without an orbit the Earth would travel off into outer space and the temperature would quickly descend below -200 degrees everywhere.

Mars. The further out from the sun, the longer a planet takes to revolve round the sun. For example, Pluto's orbit takes over 200 (Earth) years.

The Sun and its attendant planets in our Solar System, revolves round the center of the "Mikey Way" Galaxy. it takes about 200 million years to make one orbit.

Yes, the Milky Way galaxy does have a revolution around its center. It takes approximately 225-250 million years for the Sun and other stars in the Milky Way to complete one full orbit around the galactic center. This motion is what gives the galaxy its spiral shape.
