The temperature on Venus can be more than 460 °C, and this must affect the weather on Venus too. Although carbon dioxide is invisible, the clouds on Venus are made up of opaque clouds of sulfuric acid, so we can't see down to the surface with telescopes.Dec 24, 2015 The climate on Venus is widely known to be unpleasant -- at the surface, the planet roasts at more than 800 degrees Fahrenheit under a suffocating blanket of sulfuric acid clouds and a crushing atmosphere more than 90 times the pressure of Earth's. The atmosphere of Venus is mostly carbon dioxide, 96.5% by volume. Most of the remaining 3.5% is nitrogen. Early evidence pointed to the sulfuric acid content in the atmosphere, but we now know that that is a rather minor constituent of the atmosphere.
Reason to visit Venus Venus is the second brightest natural object in the sky. Venus is sometimes referred to as the “morning star” and “evening star”. One day on Venus is longer than one year. Venus is named after the Roman goddess of love and beauty. Venus is sometimes called Earth's sister planet.
Venus does not have any moons or rings.
Venus is nearly as big as the Earth with a diameter of 12,104 km.
Venus is thought to be made up of a central iron core, rocky mantle and silicate crust.
A day on the surface of Venus (solar day) would appear to take 117 Earth days.
A year on Venus takes 225 Earth days.
The surface temperature on Venus can reach 471 °C.
With an average temperature of minus 288 degrees Fahrenheit Saturn is a pretty cool planet. Although there are some small differences as one travels from the equator to the poles much of Saturn's temperature variation is horizontal. When viewed through a telescope, it is seen as a golden sphere crossed by a series of lightly colored bands parallel to the equator. Saturn is covered with a thick atmosphere made up of hydrogen and helium.. Saturn's temperature is believed to be about -270 degrees Fahrenheit or -168 degrees Celsius
It is the fifth brightest object in the solar system and is also easily studied through binoculars or a small telescope.
Saturn was known to the ancients, including the Babylonians and Far Eastern observers.
It is named for the Roman god Saturnus, and was known to the Greeks as Cronus.
Saturn is the flattest planet.
Its polar diameter is 90% of its equatorial diameter, this is due to its low density and fast rotation. Saturn turns on its axis once every 10 hours and 34 minutes giving it the second-shortest day of any of the solar system’s planets.
Like the rest of the planet, the atmosphere of Saturn is made up approximately 75% hydrogen and 25% helium, with trace amounts of other substances like water ice and methane.
