  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). [ 126 ] [ 127 ] In 1995, the Magellan spacecraft imaged a highly reflective substance at the tops of the highest mountain peaks, a " Venus snow " that ...

  3. Atmosphere of Venus - Wikipedia

    en.wikipedia.org/wiki/Atmosphere_of_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] It is much denser and hotter than that of Earth; the temperature at the surface is 740 K (467 °C, 872 °F), and the pressure is 93 bar (1,350 psi), roughly the pressure found 900 m (3,000 ft) under water on ...

    The planetary equilibrium temperature is a theoretical temperature ... Venus has an effective temperature of ... 212 °F) in the daytime and 100 K (− ...

  5. Life on Venus - Wikipedia

    en.wikipedia.org/wiki/Life_on_Venus

    Although there is little possibility of existing life near the surface of Venus, the altitudes about 50 km (31 mi) above the surface have a mild temperature, and hence there are still some opinions in favor of such a possibility in the atmosphere of Venus. [34] [35] The idea was first brought forward by German physicist Heinz Haber in 1950. [36]

  6. Terraforming of Venus - Wikipedia

    en.wikipedia.org/wiki/Terraforming_of_Venus

    This requires Venus's temperature to be reduced, first to the liquefaction point, requiring a temperature less than 304.128(15) K [32] (30.978(15) °C or 87.761(27) °F) and partial pressures of CO 2 to bring the atmospheric pressure down to 73.773(30) bar [32] (carbon dioxide's critical point); and from there reducing the temperature below 216 ...

  7. Geology of Venus - Wikipedia

    en.wikipedia.org/wiki/Geology_of_Venus

    The hemispheric view of Venus, as revealed by more than a decade of radar investigations culminating in the 1990–1994 Magellan mission, is centered at 180 degrees east longitude. The geology of Venus is the scientific study of the surface, crust, and interior of the planet Venus. Within the Solar System, it is the one nearest to Earth and ...

  8. Observations and explorations of Venus - Wikipedia

    en.wikipedia.org/wiki/Observations_and...

    On rare occasions, Venus can actually be seen in both the morning (before sunrise) and evening (after sunset) on the same day. This scenario arises when Venus is at its maximum separation from the ecliptic and concomitantly at inferior conjunction; then one hemisphere (Northern or Southern) will be able to see it at both times. This opportunity ...

  9. 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.
