Some will say you're obviously brainwashed ignoring those who sacrificed themselves for Freedom/Life
Impressive,
you really drank the Trump KoolAid.
Why is Venus so hot?
The large amount of CO2 in the atmosphere together with water vapour and sulfur dioxide create a strong greenhouse effect, trapping solar energy and raising the surface temperature to around 740 K (467 °C), [13] hotter than any other terrestrial planet in the Solar System, even that of Mercury despite being located farther out from the Sun and receiving only 25% of the solar energy (per unit area) Mercury does.[ citation needed] The average temperature on the surface is above the melting points of lead (600 K, 327 °C), tin (505 K, 232 °C), and zinc (693 K, 420 °C). The thick troposphere also makes the difference in temperature between the day and night side small, even though the slow retrograde rotation of the planet causes a single solar day to last 116.5 Earth days. The surface of Venus spends 58.3 days in darkness before the sun rises again behind the clouds. [1]

A major consequence of Venus’s massive atmosphere is that it produces an enormous greenhouse effect, which intensely heats the planet’s surface. Because of its bright continuous cloud cover, Venus actually absorbs less of the Sun’s light than does Earth. Nevertheless, the sunlight that does penetrate the clouds is absorbed both in the lower atmosphere and at the surface. The surface and the gases of the lower atmosphere, which are heated by the absorbed light, reradiate this energy at infrared wavelengths. On Earth most reradiated infrared radiation escapes back into space, which allows Earth to maintain a reasonably cool surface temperature. On Venus, in contrast, the dense carbon dioxide atmosphere and the thick cloud layers trap much of the infrared radiation. The trapped radiation heats the lower atmosphere further, ultimately raising the surface temperature by hundreds of degrees. Study of the Venusian greenhouse effect has led to an improved understanding of the more subtle but very important influence of greenhouse gases in Earth’s atmosphere and a greater appreciation of the effects of energy use and of other human activities on Earth’s energy balance
