[179][180], The United States' exploration of Venus had its first success with the Mariner 2 mission on 14 December 1962, becoming the world's first successful interplanetary mission, passing 34,833 km (21,644 mi) above the surface of Venus, and gathering data on the planet's atmosphere. Misstated as "Ganiki Chasma" in the press release and scientific publication. [204] The Greeks used the names Phōsphoros (Φωσϕόρος), meaning "light-bringer" (whence the element phosphorus; alternately Ēōsphoros (Ἠωσϕόρος), meaning "dawn-bringer"), for the morning star, and Hesperos (Ἕσπερος), meaning "Western one", for the evening star. On Sept. 14, 2020, a new planet was added to the list of potentially habitable worlds in the Solar System: Venus. Again, that’s a little smaller than Earth. [227][228] Members of that commission have since distanced themselves from the IAU statement, claiming that it had been published without their knowledge or approval. In comparison, Mount Everest is only 5.4 miles (8.8 km) above Earth's sea level. The highest mountain on Venus, Maxwell Mons, lies on the northern continent of Ishtar Terra, 7 miles (11 km) above the average surface level of the planet. [163] In the 12th century, the Andalusian astronomer Ibn Bajjah observed "two planets as black spots on the face of the Sun"; these were thought to be the transits of Venus and Mercury by 13th-century Maragha astronomer Qotb al-Din Shirazi, though this cannot be true as there were no Venus transits in Ibn Bajjah's lifetime. Venus is the brightest object in the sky after the Sun and the Moon, and sometimes looks like a … Aphrodite Terra, the largest of three continent-sized highland areas (terrae) on the planet Venus. Solar System â†’ Local Interstellar Cloud â†’ Local Bubble â†’ Gould Belt â†’ Orion Arm â†’ Milky Way â†’ Milky Way subgroup â†’ Local Group → Local Sheet → Virgo Supercluster → Laniakea Supercluster â†’ Observable universe â†’ UniverseEach arrow (→) may be read as "within" or "part of". Then, Venus Express by the European Space Agency (ESA) entered orbit around Venus in April 2006. Venus has a mean radius of 3,760 miles, or 6,052 kilometers. A day on Venus lasts 243 Earth days. [231], Subsequent analysis of the data-processing used to identify phosphine in the atmosphere of Venus has raised concerns that the detection-line may be an artefact.

[198] The word Shukra is also associated with semen, or generation. In comparison, the difference between Mount Everest and Earth's lowest point, in the Marianas Trench, is approximately 12 miles (20 km). The Venusian continents are raised areas with no relation to the plate tectonics that form land masses on Earth; of course, there are no oceans on Venus to divide them, only volcanic plains. The planet remains essentially spherical. Like its size, its density is comparable to Earth at 5.243 grams per cubic centimeter. [203] The cycles of Venus were important to their calendar. Venus's extreme temperature and atmospheric pressure make water-based life as currently known unlikely. [170][171] Venus' atmosphere was observed in 1790 by German astronomer Johann Schröter. The discovery prompted NASA administrator Jim Bridenstine to publicly call for a new focus on the study of Venus, describing the phosphine find as "the most significant development yet in building the case for life off Earth". How on Earth is the commission publishing statements that claim to represent its membership when they are not even consulted? Join our Space Forums to keep talking space on the latest missions, night sky and more! Most planets in the solar system, including Earth, spin so rapidly that they bulge slightly at the middle, creating a radius that differs at the poles and the equator. It traps heat and makes Venus very hot. Neel: That’s another big question on the minds of a lot of scientists and engineers. So, unfortunately, you won’t be able to feed your little brother to your Venus flytrap even when it is fully grown. It is thought that billions of years ago, Venus might have had a similar climate as the one on Earth. Grasping the insect with tweezers, gently insert it into the trap in such a way that a piece of it makes … Shukra which is used in Indian Vedic astrology[197] means "clear, pure" or "brightness, clearness" in Sanskrit. It takes sunlight 6 minutes to travel from the Sun to Venus. brings you the latest images, videos and news from America's space agency. Conditions on the Venusian surface differ radically from those on Earth because its dense atmo… Venus is one of the four terrestrial planets in the Solar System, meaning that it is a rocky body like Earth. [175] Later work in the 1950s showed the rotation was retrograde. Its almost featureless disc gave no hint what its surface might be like, and it was only with the development of spectroscopic, radar and ultraviolet observations that more of its secrets were revealed. Venus has an active surface, including volcanoes! In Sumerian religion, Inanna was associated with the planet Venus. Some scientists have speculated that thermoacidophilic extremophile microorganisms might exist in the cooler, acidic upper layers of the Venusian atmosphere. The surface temperature on Venus can reach 471 °C. He suggested this was due to a dense, yellow lower atmosphere with high cirrus clouds above it. [93] Similar conclusions have been reached by other studies. Nov. 30, 1954: Meteorite falls on woman in Alabama. [212][213][214] Such speculations go back to 1967, when Carl Sagan and Harold J. Morowitz suggested in a Nature article that tiny objects detected in Venus's clouds might be organisms similar to Earth's bacteria (which are of approximately the same size): The atmospheric pressure and temperature fifty kilometres above the surface are similar to those at Earth's surface. Venus… The expected mature width size of Venus flytraps is 5 inches (12.7 cm) in diameter. Launch windows to Venus only opened up at about every 19 months. [177] These three features are now the only ones on Venus that do not have female names. [154] In Inanna and Shukaletuda, Shukaletuda is described as scanning the heavens in search of Inanna, possibly searching the eastern and western horizons. [225][226], A statement was published on October 5, 2020 by the organizing committee of the International Astronomical Union's commission F3 on astrobiology, in which the authors of the September 2020 paper about phosphine were accused of unethical behaviour, and criticized for being unscientific and misleading the public. In 1974, Mariner 10 swung by Venus on its way to Mercury and took ultraviolet photographs of the clouds, revealing the extraordinarily high wind speeds in the Venusian atmosphere. ", "Phosphine Gas in the Cloud Decks of Venus", "NASA chief calls for prioritizing Venus after surprise find hints at alien life", "Statement from Commission F3 (Astrobiology) of the IAU on Press Reports regarding Detection of Phosphine in Venus", "The IAU would like to clarify that a recent statement about the press coverage of the discovery of phosphine in the atmosphere of Venus originated from the Organizing Committee of the IAU Commission F3 and not from the IAU Executive, nor the IAU Commission F3 membership", "Absolutely shocked & dismayed by this statement from the @IAU_org - as a member of IAU Com F3, I completely disagree - this is how science progresses", "I'm also a member of F3 and I didn't even know about the letter until it was published this morning. [172] The atmosphere complicated efforts to determine a rotation period for the planet, and observers such as Italian-born astronomer Giovanni Cassini and Schröter incorrectly estimated periods of about 24 h from the motions of markings on the planet's apparent surface. Venus is thought to be made up of a central iron core, rocky mantle and silicate crust. Orbit and Rotation Second planet from the Sun in the Solar System, This article is about the planet. Both planets are much farther away from the Earth than the moon and only cover a tiny dot of the sun’s disk. Receive mail from us on behalf of our trusted partners or sponsors? Aphrodite Terra lies just to the south of the equator. Findings from the first missions to Venus showed the reality to be quite different, and brought this particular genre to an end. When Venus is furthest from the Sun in the sky, it shows a half-lit phase, and when it is closest to the Sun in the sky, it shows as a crescent or full phase. The diameter of Venus is about 7,520 miles (12,100 kilometers), approximately 400 miles (644 kilometers) smaller than that of the Earth. [218][219], In September 2020, a team of astronomers led by Jane Greaves from Cardiff University announced the likely detection of phosphine, a gas not known to be produced by any known chemical processes on the Venusian surface or atmosphere, in the upper levels of the planet's clouds. — Nola Taylor Redd, Contributor. Venus spins the opposite direction of Earth and most other planets. Often called Earth's sister planet, Venus is the closest in size, with a mass of more than 80 percent that of our planet and a diameter of only a few miles less. Venus has a thick atmosphere. Ishtar Terra is about the size of Australia, and contains the four mountain ranges of Venus, providing potential evidence that the planet's surface may be in motion. [167][168], The 1639 transit of Venus was accurately predicted by Jeremiah Horrocks and observed by him and his friend, William Crabtree, at each of their respective homes, on 4 December 1639 (24 November under the Julian calendar in use at that time). In the second century, in his astronomical treatise Almagest, Ptolemy theorized that both Mercury and Venus are located between the Sun and the Earth. Venus is known as Kejora in Indonesian and Malaysian Malay.
