Planetaryring

A planetary ring is a ring of dust and other small particles orbiting around a planet in a flat disc-shaped region. The most notable planetary rings are those of Saturn, but rings of varying sizes have been observed around each of the four gas giants in the Solar System (Jupiter, Saturn, Uranus, and Neptune). These rings are composed of many small particles that can range in size from micrometers to meters. The exact composition of the particles varies but they are generally made of almost pure water ice with a smattering of rocky debris and dust. The origin of planetary rings is not fully understood, but they are thought to be the result of the destruction of moons or moonlets by the gravitational forces of their parent planet, or the remnants of the protoplanetary disk that formed the planet. In Hebrew, planetary ring is translated as טבעת פלנטרית. In other languages, planetary ring is translated as planetenring in German, anillo planetario in Spanish, and anneau planétaire in French.
