From far away, Saturn's rings look like smooth, bright bands. They are actually made of an enormous number of pieces of ice, dust and rock. Some are as small as grains, while others may be larger than a house.
Every piece travels around Saturn under the influence of gravity. From our viewpoint they blend into luminous bands because there are so many of them and their icy surfaces reflect sunlight. Darker gaps contain less material.
The rings stretch across a huge distance but are surprisingly thin compared with their diameter. Their exact origin is still being studied. They may be the remains of a moon or another body that broke apart in Saturn's powerful gravitational field.
A small telescope can reveal the rings as a distinct shape around the planet. Their apparent tilt changes over the years, so Saturn does not always present the same view to observers on Earth.
