  2. Venus - Wikipedia

    en.wikipedia.org/wiki/Venus

    The highest point on Venus, Maxwell Montes, is therefore the coolest point on Venus, with a temperature of about 655 K (380 °C; 715 °F) and an atmospheric pressure of about 4.5 MPa (45 bar). [ 127 ] [ 128 ] In 1995, the Magellan spacecraft imaged a highly reflective substance at the tops of the highest mountain peaks, a " Venus snow " that ...

  3. List of hottest exoplanets - Wikipedia

    en.wikipedia.org/wiki/List_of_hottest_exoplanets

    For comparison, the hottest planet in the Solar System is Venus, with a temperature of 737 K (464 °C; 867 °F). List of hottest exoplanets irradiated by a nearby star [ edit ]

  4. Planetary equilibrium temperature - Wikipedia

    Consequently, such planets have surface temperatures higher than their effective radiation emission temperature. For example, Venus has an effective temperature of approximately 226 K (−47 °C; −53 °F), but a surface temperature of 740 K (467 °C; 872 °F).

  5. Atmosphere of Venus - Wikipedia

    en.wikipedia.org/wiki/Atmosphere_of_Venus

    The atmosphere of Venus is the very dense layer of gases surrounding the planet Venus. Venus's atmosphere is composed of 96.5% carbon dioxide and 3.5% nitrogen , with other chemical compounds present only in trace amounts. [ 1 ]

  6. Life on Venus - Wikipedia

    en.wikipedia.org/wiki/Life_on_Venus

    In 1962, Mariner 2, the first successful mission to Venus, measured the planet's temperature for the first time, and found it to be "about 500 degrees Celsius (900 degrees Fahrenheit)." [ 14 ] Since then, increasingly clear evidence from various space probes showed Venus has an extreme climate, with a greenhouse effect generating a constant ...

  7. Terraforming of Venus - Wikipedia

    en.wikipedia.org/wiki/Terraforming_of_Venus

    The terraforming of Venus or the terraformation of Venus is the hypothetical process of engineering the global environment of the planet Venus in order to make it suitable for human habitation. [1] [2] [3] Adjustments to the existing environment of Venus to support human life would require at least three major changes to the planet's atmosphere ...

  8. Surface features of Venus - Wikipedia

    en.wikipedia.org/wiki/Surface_features_of_Venus

    The surface conditions on Venus are more extreme than on Earth, with temperatures ranging from 453 to 473 °C and pressures of 95 bar. [3] Venus lacks water, which makes crustal rock stronger and helps preserve surface features. The features observed provide evidence for the geological processes at work.

  9. Water on Venus - Wikipedia

    en.wikipedia.org/wiki/Water_on_Venus

    This means the habitable zone was stretched from Venus to Earth (and possibly to Mars), before eventually Solar maxima began creating greenhouse gases in Venus’ atmosphere, making the atmosphere thicker, evaporating away all liquid water on the planets surface. Studies have proven that Venus needed liquid water three billion years ago to be ...
