<p>Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. </p>It is a gas giant with a mean radius of about nine times that of Earth. It only has one-eighth the density of Earth; however, with its larger volume, Saturn is over 95 times more massive. Saturn is named after the Roman god of riches and agriculture; its astronomical symbol (♄) represents the god's sickle. Saturn's interior is most likely composed of a core of iron--nickel and stone (silicon and oxygen compounds). Its center is surrounded by an intermediate layer of liquid hydrogen, a deep layer of metallic hydrogen and helium, and finally a gaseous coating. Saturn has a hue because of ammonia crystals at its atmosphere. An electric current within the hydrogen layer is thought to contribute to the planetary magnetic field, which is weaker than the Earth's, but has a magnetic moment of Saturn 580 times that of Earth because of Saturn's larger dimensions.



Saturn's magnetic field strength is of Jupiter's. The outer atmosphere is usually bland and lacking in contrast, although features can appear. Wind speeds on Saturn can reach 1,800 km/h (1,100 mph; 500 m/s), greater compared to Jupiter, but not as large as those on Neptune. In January 2019, astronomers reported that a day around the planet Saturn has been decided to be 10h 33m 38s + 1m 52s− 1m 19s, according to studies of the world's C Ring.The world's most famous feature is its prominent ring system, which is composed mostly of ice particles, with a smaller amount of rocky debris and dust. At least 82 moons are known to orbit Saturn, of which 53 are named. Titan, the second-largest in the Solar System, and Saturn's largest moon, is the only moon in the Solar System to have a substantial atmosphere, and is larger than the planet Mercury, although less massive.

Venus is the second planet from sunlight. It is named after the Roman goddess of love and beauty. As the thing in the night sky after the Moon, Venus may be, on occasion, visible to the naked eye in broad daylight and can cast shadows. Venus lies within Earth's orbit, and never appears to venture either setting in the west just after dusk or rising in the east a bit before sunrise. Venus orbits the Sun every 224.7 Earth days. Having a rotation period of 243 Earth days, it takes longer to rotate about its axis than any other planet in the Solar System and does so in the opposite direction to all but Uranus (meaning that the Sun rises in the west and sets in the east). Venus does not have any moons, a distinction it shares only with Mercury among planets in the Solar System.Venus is a terrestrial planet and is sometimes called Earth's"sister planet" because of their similar size, mass, proximity to the Sun, and bulk composition. It is different from Earth in different respects. It's the atmosphere of the four planets, consisting of over 96% carbon dioxide. The atmospheric pressure at the planet's surface is 92 times that of Earth, or roughly the pressure found 900 m (3,000 feet ) underwater on Earth. Venus is by far the hottest planet in the Solar System, with a mean surface temperature of 735 K (462 °C; 863 °F), even though Mercury is closer to the Sun. Venus is shrouded by an opaque layer of reflective clouds of sulfuric acid, preventing its surface from being seen from space in light.



It might have had water oceans before, as the temperature rose because of a runaway greenhouse effect but these could have vaporized. The water has photodissociated, and the hydrogen that is free has been swept into space by the solar wind due to the lack of a planetary magnetic field. Venus's surface is a sterile desertscape interspersed with slab-like rocks and is periodically resurfaced by volcanism. Venus has been a significant fixture in human civilization for as long as records have existed. It has been made sacred to gods of many cultures, and has been a inspiration for writers and poets as the morning star and evening star. Venus was the first planet to have its motions plotted across the sky, as early as the second millennium BC.As the planet with the nearest approach to Earth, Venus has been a prime target for early interplanetary exploration. It was the first planet beyond Earth visited by a spacecraft (Mariner 2 in 1962), and also the first to be successfully landed on (by Venera 7 in 1970). The thick clouds of venus render observation of its surface impossible in visible light, and the detailed maps did not emerge before the Magellan orbiter's coming in 1991. Plans have been proposed for more complex missions or rovers, but the hostile surface conditions of Venus hinder them. In January 2020, astronomers reported evidence that suggests that Venus is volcanically active.
