Its surface features, long hidden under the constant cloud cover, were finally mapped by the Magellan space probe using radar in [[TheNineties the 1990s]]. The highest mountain is Maxwell Montes, almost 7 miles above the average surface level. If you stood on its peak, it'd be a downright chilly 380°C / 716°F, and a mere 60 atmospheres of pressure. The culprit for all this heat is the greenhouse effect--Earth's atmosphere is less than 1% carbon dioxide, while Venus's is over 90% carbon dioxide. Earth started with the same amount, [[SealedEvilInACan but it ended up trapped in carbonate rock]]. Venus also started with the same amount of water as the Earth had, but it remained in vapor form (300 atmospheres worth) and created [[UpToEleven a super greenhouse effect]] with temperatures in the ''thousands'' of degrees. [[note]]This plus the slow rotation probably wrecked any chance at plate tectonics; instead of plates constantly sliding against each other, [[LethalLavaLand there seems to be intermittent planet-wide volcanism wiping out many of the planet's surface features every billion years or so]].[[/note]] Eventually the water molecules dissociated into hydrogen and oxygen and escaped into space and sank down and fused with the rocks respectively, leaving Venus high and dry. Due to Venus being mythologically associated with femininity, by convention all geographic features there are named after women or female entities, except for Maxwell Montes and Alpha and Beta Regio. [[note]]These features were first detected by ground-based radar in the mid-1960's; Alpha and Beta Regio were the first two terrain features to be isolated, and Maxwell Montes was named after James Clerk Maxwell, the formulator of the theory and equations of electromagnetism that ultimately led to the invention of radar.[[/note]] There is some argument over whether the proper adjective is 'Venusian', 'Venerean', or 'Cytherean' -- just don't use 'Venereal'.

At some point in the planet's early history, some big huge honkin' planetesimal struck it at an oblique angle, causing it to rotate very slowly ''backwards'' when compared with all the other planets in the Solar system. As a result of this super-slow rotation, a Cytherean solar day is nearly as long as a Venusian year. Not that you'd be able to ''see'' much difference between day and night while on the surface. Whether you're on the day side or the night side, you'll see a hazy overcast sky that's about the same brightness everywhere--assuming you survive the lack of oxygen, the crushing pressures, and the hellish temperatures, that is. This slow rotation is also responsible for the current state of Venus's atmosphere. Venus rotates far too slowly to produce a strong magnetic field, leaving the water vapor that was once in its atmosphere vulnerable to dissociation by solar radiation. If circumstances had left Venus rotating at a similar rate to Earth, its magnetic field would be nearly as strong, and then who knows what the planet would be like.

In addition to this, [[http://space.stackexchange.com/questions/2237/how-long-will-it-be-light-on-venus-at-night the refraction of the Venusian atmosphere is so high]] that it would look as if you was in a basin/valley (calculations show too that at a height of 35 kilometers you'd be able to see ''the entire planet'' (read: clouds) in a panoramic view). Objects dropped to the ground would fall very slowly because of the atmospheric density and moving would be rather similar to swimming for the same reasons. Meanwhile the sky would just show a faint sliver of light where the Sun was located, and in the night side besides lightning and active volcanoes illuminating the clouds you'd be able to see the rocks with a very faint red glow. Have fun while you're there.[[/note]]. This slow rotation is also responsible for the current state of Venus's atmosphere.

* In the arcade game ''Solar Warrior'', the second stage takes in the planet Venus. It's depicted there as a jungle world with dinosaurs, huge insects, carnivorous plants, and of course [[EverythingIsTryingToKillYou]]-

Aside of the Moon, Venus is also the best place of the Solar System to see our planet. From there, Earth appears as a dazzling blue star that with a telescope would give a lot of fun as weather patterns change and continents/oceans move because of its rotation. UsefulNotes/TheMoon would appear almost as bright as we see UsefulNotes/Jupiter, and while much more dull than Earth it would give even more fun as the former orbits the latter and both bodies approached, moved away, and in some cases overlapped. Nice AlienSky, if all those clouds were not in the middle.

UsefulNotes/TheMoon would appear almost as bright as we see UsefulNotes/Jupiter, UsefulNotes/{{Jupiter}}, and while looking much more dull than Earth it would give even contribute with still more fun for astronomers as the former orbits the latter and both bodies approached, moved away, and in some cases overlapped. Nice AlienSky, if all those clouds were not in the middle.

* StephenKing's short story ''[[Literature/NightShift I Am The Doorway]]'' concerns a manned mission to Venus that goes horribly, horribly wrong (you want an idea how wrong, [[https://le0pard13.files.wordpress.com/2014/10/3eb908c333195286e7-0.jpg look at the cover]]). Because it was written in 1971, near the beginning of the ''Venera'' program, it spans the gap between our early, speculative take on Venus and our full, horrified understanding of its true nature. Nonetheless, being King, it contains some fittingly chilling descriptions of the planet's surface that would turn out to be unwittingly prescient [[http://i.imgur.com/lh4a46c.jpg once the pictures came in]].

* In ''Series/{(Exosquad}}'', Venus has been terraformed and inhabited by humanity. One of the main cast members, Nara Burns, was born there. [[spoiler: Her parents and brother are all dead by the end of the series as a result of the war with the Neo-Sapiens.]]
