Venus : the planet second in order from the sun — Webster

OneLook, Free Dictionary, Wiktionary, Urban Dictionary

Encyclopedia

Venus is the second planet from the Sun, orbiting it every 224.7 Earth days. The planet is named after Venus, the Roman goddess of love and beauty. After the Moon, it is the brightest natural object in the night sky, reaching an apparent magnitude of −4.6, bright enough to cast shadows. Because Venus is an inferior planet from Earth, it never appears to venture far from the Sun: its elongation reaches a maximum of 47.8°. Venus reaches its maximum brightness shortly before sunrise or shortly after sunset, for which reason it has been known as the Morning Star or Evening Star. Venus is classified as a terrestrial planet and it is sometimes called Earth’s “sister planet” due to the similar size, gravity, and bulk composition. — Wikipedia

  • Did Venus ever have oceans?
    on October 13, 2021 at 3:40 pm

    Astrophysicists have investigated the past of Venus to find out whether Earth's sister planet once had oceans.

  • Earth and Venus grew up as rambunctious planets
    on September 27, 2021 at 5:19 pm

    Using machine learning and simulations of giant impacts, researchers found that the planets residing in the inner solar system were likely born from repeated hit-and-run collisions, challenging conventional models of planet formation.

  • The weather forecast for Venus
    on July 21, 2021 at 4:07 pm

    Little is known about the weather at night on Venus as the absence of sunlight makes imaging difficult. Now, researchers have devised a way to use infrared sensors on board the Venus orbiter Akatsuki to reveal the first details of the nighttime weather of our nearest neighbor. Their analytical methods could be used to study other planets including Mars and gas giants as well.

  • Trace gas phosphine points to volcanic activity...
    on July 12, 2021 at 7:19 pm

    Last autumn, researchers reported finding the gas phosphine in trace amounts in Venus' upper atmosphere, raising the slim possibility of a biological signature. Now scientists say that the phosphine's chemical fingerprints support a different find: evidence of explosive volcanoes.

  • 'Pack ice' tectonics reveal Venus' geological...
    on June 21, 2021 at 8:05 pm

    A new analysis of Venus' surface shows evidence of tectonic motion in the form of crustal blocks that have jostled against each other like broken chunks of pack ice.

  • Ten mysteries of Venus
    on October 21, 2021 at 3:20 pm

    The surface of Venus is completely inhospitable for life: barren, dry, crushed under an atmosphere about 90 times the pressure of Earth's and roasted by temperatures two times hotter than an oven. But was it always that way? Could Venus once have been a twin of Earth—a habitable world with liquid water oceans? This is one of the many mysteries associated with our shrouded sister world.

  • Astronomers detect signs of an atmosphere...
    on October 20, 2021 at 3:00 pm

    Young planetary systems generally experience extreme growing pains, as infant bodies collide and fuse to form progressively larger planets. In our own solar system, the Earth and moon are thought to be products of this type of giant impact. Astronomers surmise that such smashups should be commonplace in early systems, but they have been difficult to observe around other stars.

  • We've spotted a planet surviving its dying star...
    on October 14, 2021 at 1:10 pm

    How will the solar system die? It's a hugely important question that researchers have considered deeply, using our knowledge of physics to create complex theoretical models. We know that the sun will eventually become a "white dwarf", a burnt stellar remnant whose dim light gradually fades into darkness. This transformation will involve a violent process that will destroy an unknown number of its planets.

  • Did Venus ever have oceans?
    on October 13, 2021 at 3:00 pm

    The planet Venus can be seen as the Earth's evil twin. At first sight, it is of comparable mass and size as our home planet, similarly consists mostly of rocky material, holds some water and has an atmosphere. Yet, a closer look reveals striking differences between them: Venus' thick CO2 atmosphere, extreme surface temperature and pressure, and sulphuric acid clouds are indeed a stark contrast to the conditions needed for life on Earth. This may, however, have not always been the case. Previous […]

    on October 6, 2021 at 7:03 pm

    The dwarf planet Vesta is helping scientists better understand the earliest era in the formation of our solar system. Two recent papers involving scientists from the University of California, Davis, use data from meteorites derived from Vesta to resolve the "missing mantle problem" and push back our knowledge of the solar system to just a couple of million years after it began to form. The papers were published in Nature Communications Sept. 14 and Nature Astronomy Sept. 30.
