It is a meteoroid. To prove my answer, here is where I went:
ask.com and I typed in what is a icy rock in outer space called?
It gave me the answer meteoroid.
Pluto, a dwarf planet.
There is no particular reason why the outer planets are gas and the inner planets are rock, but the outer planets have icy cores because they are all far away from the sun.
An icy mass that orbits the sun is called a comet.
the rings around our planets are made out of icy dust particles and frozen gases
Terrestrial planets have a rock composition (and are also smaller), giant planets are made up from mostly hydrogen, helium and icy and rocky materials. However, the two giants, Jupiter and Saturn, have a very small inner core of icy and rocky materials and a larger outer core of hydrogen and helium. The two subgaints, Neptune and Uranus, have a larger inner core of icy and rocky material and a smaller outer layer of hydrogen, helium and icy materials.
No. The Kupier belt is a collection of icy objects in the outer solar system.
