Not necessarily. In a few billion years, our sun will exhaust its nuclear fuel, and, for all practical purposes, "die". Planets closer to the sun will be consumed, but planets farther away will be flung away.
It's very very probable that such an event has happened sometime in the past somewhere in the universe, so much so, that I'd be willing to bet my left arm on it. Those planets are drifting, until captured by another gravitational entity.
But the creation of planets most likely has to start with the creation of a star, if that's what you were asking. Hydrogen and Helium will always combine to form the lower elements required in a star first before creating the higher elements that are required for a "planet".
Of course, there are quantum loopholes that would allow anything (and I mean anything, like a giant space breathing cat to spontaneously appear in the center of the milky way and to disappear a split second later), but we'll discount those.

How many days does it take each planet to rotate around the sun?
Each planet is different, due to size and distance from the sun. The Earth takes 365 days or 1 year to rotate.
What is the curved path of a planet around the sun?
The curved path is called the orbit. Each planet has its own orbit. Some are faster and some are slower. They are caused by the gravity of the planet and the sun
What point in a planet's orbit is closest to the sun?
The perihelion is the closest point to the Sun in the orbit of a planet.It is different for each planet based on the elliptical variation, but will always occur at the same point in each orbit.
How does the earth sun and moon move around each other?
The sun does not orbit or move around the Earth and moon because the Earth has to orbit the sun while the moon orbits the earth.
How does gravity affect planetary motion?
The mutual gravitational forces that attract a planet and the sun to each other are responsible for keeping the planet in orbit around the sun.
Why do planets revlolve around the sun?
Inertia is trying to keep each planet moving in a straight line, and the sun's gravity is trying to pull each planet into the sun. The resultant of those two vectors is the orbital path each planet follows.
How does the temperature of each planet relates to its distance from the sun?
It relates because if the planet is closer resieves more light from the sun.
Why are the revolutionary times of each planet different?
the farther out a planet is the less gravity is acting on the planet by the sun
What are the distances from each planet to the sun?
10000 klm
Is it true that each planet makes one revolution each year?
depends on what you mean. The planets revolve by themselves and around the sun so if you mean just a rotation of a planet then no. If you mean around the sun it depends on how your thinking about it. If you're talking about 365 earth days, then no. Each planet moves at a different speed around the sun and the farther from the sun, the slower the rotation.
Which direction is each planet?
All the planets are in motion about the sun. Each at different speeds and distances. The direction to each planet therefore changes over time.
How many days does it take each planet to rotate around the sun?
Each planet is different, due to size and distance from the sun. The Earth takes 365 days or 1 year to rotate.

What point in a planet's orbit is closest to the sun?
The perihelion is the closest point to the Sun in the orbit of a planet.It is different for each planet based on the elliptical variation, but will always occur at the same point in each orbit.
How long does it take for each planet to rotate around the sun?
23.56
The journey that each planet makes around the sun is called what?
orbit
What is the average distance from the sun to each planet?
17 and a half hours
