Size
comparison among Earth, Saturn, and Saturn's rings.
|
Earth is a big
place. Compared to an afternoon walk -- it sure is. But
compared to some other places, it seems pretty small.
Saturn 6th PLANET
from the sun, at a mean distance of 886.7 million mi. (1.4270 billion
km). It has an equatorial diameter of 74,980 mi. (120,660 km) and an
atmosphere of hydrogen, helium, and traces of methane and ammonia.
Saturn's most remarkable feature is its ring system, composed of
billions of water-ice particles orbiting around the planet. The main
rings are at distances ranging from 4,140 to 49,880 mi. (6,670 to
80,270 km) above the cloud tops, and two other tenuous rings orbit
much more distantly.
Earth fifth
largest planet of the Solar System and the only one known to support
life. Its mean distance from the SUN is c.93 million mi. (150 million
km). Gravitational forces have molded the earth into a spherical shape
that bulges slightly at the equator (equatorial diameter: c.7,926
mi./12,760 km; polar diameter: 7,900 mi./12,720 km).
