What relationship do you observe between a planet’s size and its proximity to the Sun?

    In our solar system, the rocky worlds seem to be closer, while the gas giants seem to be further out. 

    In other solar systems, this doesn't appear to be a rule... we've seen "Hot Jupiters" - large, gas giant worlds that orbit close in to their Sun, while in another solar system, a gas giant was the closest world, followed by a rocky world, then another gas giant, then a rocky world... In still another solar system, a large Jupiter-sized world has an orbit much like that of a comet - swinging in close to its star at one extreme, then far out into space in another.

    There is a relationship between the planet's average density ,and its distance from the sun -- which is not so random.

    With only one solar system to observe, we really can't determine any relationship or draw any conclusions.

    I observe that any vague relationship we might have suspected based on our solar system has been totally squashed by the burgeoning detection of exoplanets.

    None whatsoever. the four closest are very similar in size (small), the fifth never happened, the 6th and 7th are huge, the 8th and 9th are big

    You'd need a statistically significant number of star-systems to observe any pattern

    In our solar system, the smaller planets, Mercury, Venus, Earth, and Mars, are closer in to the sun than the large ones, Neptune, Jupiter, Saturn, Uranus.  Which actually is one reason Pluto was drummed out of the planets for our solar system.  It's too small.

    An inconsistent one.
