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.

<p>Jupiter is the fifth planet from the Sun and the largest in the Solar System. </p>It's a gas giant with a mass one-thousandth that of the Sun, but two-and-a-half times that of the rest of the planets in the Solar System. Jupiter is one of the objects visible to the naked eye in the night sky, and has been known since before recorded history. It's named after the Roman god Jupiter. Jupiter can be bright for its reflected light to cast shadows, and is on average the natural thing in the night sky after the Moon and Venus, when viewed from Earth. Though helium contains only about a tenth of the number of molecules, jupiter is composed of hydrogen with a quarter of its mass being helium. It may also have a core of elements that are heavier, but like the other giant planets, Jupiter lacks a solid surface that is well-defined. Due to its rapid rotation, the world's shape is that of an oblate spheroid (it has a slight but noticeable bulge around the equator). The outer air is visibly segregated into bands at different latitudes, leading to turbulence and storms across their bounds. A result that is notable is the Great Red Spot, a storm that's known to have been around since at least the 17th century when telescope first saw it.



Surrounding Jupiter is a faint planetary ring system and a magnetosphere. Jupiter has 79 moons, including the four Galilean moons discovered by Galileo Galilei in 1610. Ganymede, the largest of them, has a diameter greater than that of the planet Mercury. Pioneer 10 was the first spacecraft to go to Jupiter, making its closest approach to the planet on December 4, 1973; Pioneer 10 recognized plasma in Jupiter's magnetic field and also found that Jupiter's magnetic tail was nearly 800 million km long, covering the whole distance to Saturn. Jupiter has been explored on a number of occasions starting with the Pioneer and Voyager flyby missions from 1973 to 1979, and by the Galileo orbiter. In February 2007, Jupiter was visited by the New Horizons probe, which used Jupiter's gravity to increase its speed and flex its trajectory en route to Pluto. The most recent probe to visit the planet is Juno, which entered into orbit around Jupiter. Future targets for mining in the Jupiter system include the likely liquid sea of its moon Europa.
