They don't - new born stars and planets are formed together.
What is the reason that life is less likely on the outermost planets compared to the innermost planets
a large baked potato takes longer to cool than a small baked potato
The gravitational pull from the sun. God put them there.
The planets revolve attracted by the gravitational force of primarily the sun and to a lesser degree the gravitational attraction of other planets. The reason for the orbit is thought to relate to the rotation of the primeval gas could which gave berth to the sun and the planets.

The outer planets are gas planets
Heat for all the planets and the main reason for the orbits of the planets.
The reason that most extrasolar planets are found close to their parent stars is that the amount and frequency of the star's motion are both higher in these planets.
there isn't actually a reason for "what are planets for" but they might be for life forms. planets are not for anything really, they just got made by gravity.
When you are 89, a reason for dying is not relevant.
Other planets appear shiny from Earth for the same reason the moon does, we see the other planets' reflected sunlight.
It is half the reason, at least. Gravity is the force pulling the planets towards the sun, but they also have a velocity working perpendicular to it. With the velocity alone, the planets would fly off into space. With gravity alone, the planets would be pulled into the sun.

It is due to the conservation of momentum.
They were being systematically killed by the Nazis.
