What are the significant features of Saturn?
Saturn is a gas giant made up mostly of hydrogen and helium. Saturn’s volume is greater than 760 Earths, and it is the second most massive planet in the solar system, about 95 times Earth’s mass. The Ringed Planet is the least dense of all the planets, and is the only one less dense than water.
Are Venus and Saturn similar?
But as close as they’ll appear in the sky, the two will look quite different, with Venus shining over eighty times brighter than Saturn. On average, Venus is the closest of the naked-eye planets, while Saturn is the farthest, which goes a long way toward explaining the difference in their brightness.
What is the most famous feature of Saturn?
The planet’s most notable feature is its prominent ring system, which is composed mainly of ice particles, with a smaller amount of rocky debris and dust. At least 83 moons are known to orbit Saturn, of which 53 are officially named; this does not include the hundreds of moonlets in its rings.
What are the significant features of Venus?
The planet is a little smaller than Earth, and is similar to Earth inside. We can’t see the surface of Venus from Earth, because it is covered with thick clouds. However, space missions to Venus have shown us that its surface is covered with craters, volcanoes, mountains, and big lava plains.
Which is better Venus or Saturn?
Venus is the dazzling “morning star,” so you can’t miss it. It’ll overpower the other planet, Saturn, which looks only about one percent as bright. That mismatch is an illusion, though. Saturn actually is by far the more impressive of the two planets.
What does Saturn look like?
Viewed from Earth, Saturn has an overall hazy yellow-brown appearance. The surface that is seen through telescopes and in spacecraft images is actually a complex of cloud layers decorated by many small-scale features, such as red, brown, and white spots, bands, eddies, and vortices, that vary over a fairly short time.
What are the geologic features of Venus?
Geologic forces at work beneath the crust create mountains, rifts, and patterns of fractures, while the sluggish winds sculpt the surface in subtler ways. Folding and Mountain Building Alpha Regio is an example of highly deformed crust called tessera. Such areas may be the oldest surfaces on Venus.
Can we get pictures of the surface of Venus?
The Soviet Union’s Venera series of robotic spacecraft make several successful landings on the surface of Venus—sending back the first data from the surface of another planet the only pictures of the Venusian surface to date. NASA’s Magellan spacecraft, in orbit around Venus, uses radar to map 98 percent of the planet’s surface.
Why is Venus the hottest planet in the universe?
Venus spins slowly in the opposite direction most planets do. Its thick atmosphere traps heat in a runaway greenhouse effect, making it the hottest planet in our solar system—with surface temperatures hot enough to melt lead. Glimpses below the clouds reveal volcanoes and deformed mountains. Explore Venus ›.
What is the surface temperature of Venus?
Venus has no moons and no rings. The planet’s surface temperature is about 900 degrees Fahrenheit (465 degrees Celsius)—hot enough to melt lead. Many scientists believe water once existed on the surface.
