Uranus and Neptune are mostly composed of gas and "ices".
However, I think the answer is Pluto. Of course, it's only a dwarf planet now.
because they are made of rocky balls and ice.
All comets, including Encke, are made of rocks, ice, dust, and frozen gases such as ammonia, methane, carbon monoxide and carbon dioxide. The center of a comet is sometimes referred to as a dirty snowball.
Comets, sometimes called a dirty snowball, are composed of ice covered by a crust. Rock, dust, and frozen gases such as carbon monoxide, carbon dioxide, methane, and ammonia make up the crust.
A comet is an object that has a tail made of gases and dust.
The walls of a radiator get dirty from the roads. This can be washed.
A comet is often described by Astronomers as a 'Dirty Snowball'. This is because a comet comprises of Ice, from frozen gases mixed with dust and other particulate matter, collected on its orbital path.

It is a cosmic body, formed from a cloud of dust and gases.

All comets, we believe, are composed of a lot of ices such as frozen carbon dioxide, nitrogen, oxygen, water, and other gasses, with a lot of dust and some rocks. Science fiction writers Jerry Pournelle and Larry Niven described a comet as a "dirty snowball".
Comets can be described as "Dirty Snowballs" and are composed of rock, dust, water ice, and frozen gases.
Halley's Comet is most probably a collection of ice, dust and rocks; a "dirty snowball" may be the most apt description. I'm not sure that "land" would fit the description.
the moon has dust because it is dirty
A comet is an object that has a tail made of gases and dust.
Jupiter is 90% hydrogen 10% helium and there are small amounts of methane, ammonia, and rock dust
