Hottest planet in the universe.

just found out today. that the hottest planet is not the one that is closest to the sun. It's Venus, Venus is the second closest planet to the Sun. Telescopes reveal little about the planet due to global cloud cover. Venus' mass and volume are quite similar to Earth's (Venus' mass is 81.5% of Earth's and its volume is 86% of Earth's). Its almost circular orbital period is 224.7 Earth days. A 0.76 albedo makes Venus the brightest planet, earning it the nickname 'the Morning Star'. (The 19th Century astronomer Franz Von Paula Gruithuisen believed that inhabitants on the planet were responsible for lighting objects in celebration of the accession of a new emperor.) Until the early 1960s, Venus was believed to possibly be oceanic even though the temperature was enough to make it a vast desert. Finally, in 1962, the Mariner 2 spacecraft passed by Venus and sent back data putting an end to this hopeful theory. The atmosphere consists almost entirely (96%) of carbon dioxide (CO2), a greenhouse gas responsible for the incredibly hot, greater than 400ºC conditions on Venus, surpassing the melting point of lead. The rest of the atmosphere is comprised of 3% nitrogen, 0.003% water vapor, and small quantities of other gases. The atmosphere rises to about 400km above the surface of the planet. The clouds situated around 30 km above the surface are rich in sulfuric acid; during precipitation the acid rain evaporates before hitting the ground. In 1970, the Soviet Union landed the first spacecraft on the planet's surface, Venera 7, which sent back information for 23 minutes before losing contact with ground control (most likely due to the temperature). On October 21, 1975, Venera 9 landed and sent back the first image of the rocky Venusian surface (thereby confirming the high temperatures), returned atmospheric data, and found the rotation period to be 243.2 days, longer than one Venusian year. A Venusian day lasts 118 Earth days, and the Sun rises in the west and sets in the east since Venus rotates in the opposite direction to Earth. I wonder if us humans, can live on Venus. if its they say that Venus is the twin planet of the Earth. can we live on Venus if planet earth became too polluted and not livable anymore? answer? The planet Venus has many of the elements found on Earth, but conditions there are not hospitable to human life. It is too hot (average 464 °C or 867°F) and the carbon dioxide atmosphere has a crushing pressure nearly 100 times that at sea level on Earth (92 bar). Under these conditions, there is also no liquid water on the planet's surface, and the only "rain" (high up in the atmosphere) consists of sulfuric acid! Floating Cities Several novel proposals have suggested establishing aerial colonies 50 kilometers above the surface, where the temperature and pressure are closer to Earth's. awwwts... I love beach but I don't like to be in hot places... so i dont think I will like it there. feed mind. soleved Labels: EVENT, Planets, something to know |
