How much hotter is venus than earth




















The long nights provide no escape from the heat, as the trapping and thermalizing effects of the cloud layers keep the surface of Venus at an inhospitably high temperature, so much so that if you added up the operational time of every lander that ever touched down on Venus' surface, it wouldn't even sum to half an Earth-day.

The very cold, polar regions of the Earth have a mean temperature far below the rest of the planet But in the right amounts, atmospheric heat-trapping can be the best thing ever to happen to a world. The blanket-like effect of the clouds and atmospheric gases lift our planet's climate into the temperate zone where life-as-we-know it has thrived for so long.

Yet early in the Solar System's history, with a cooler Sun and a much thinner atmosphere, Venus was probably similar in temperature to Earth's today. It likely had the same potential for life and biological processes, but a runaway catastrophe created the permanent inferno that's inhabited our sister world for billions of years. While Earth isn't at risk of the same fate, Venus stands as both the hottest world in our Solar System and a cautionary tale of an out-of-control greenhouse effect.

As we come to better understand the processes that drive the Earth's climate and temperature, it's our responsibility to steer our planet in the right direction. The link between the Sun, the atmosphere and the planet's fate is written all over each world in our Solar System. It's up to humanity to learn those lessons and decide what we do next.

Could life exist on Venus? Why is Venus so hot? Lead would melt on the surface of the planet, where the temperature is around F C. Temperatures on Venus remain consistent over time.

For one thing, the planet takes Earth days to spin once on its axis and it spins backwards, at that; on Venus, the sun rises in the west and sets in the east. The nights on Venus are as warm as the days. Venus also has a very small tilt of only 3. On our planet, it is the tilt that provides us with the change in seasons; the hemisphere slanted closer to the sun feels the heat of spring and summer.

You know, the ones where an increase in pressure equals an increase in temperature? Is there a good reason or reasons why I should NOT have? Or does atmospheric pressure work differently at different orbits?

Again: the temperature at the 1-bar level of the Venusian atmosphere is — dare I say it — habitable, despite the CO2 content. Think I agree with Meek Gee — sure a gas heats up when you compress it, but once a steady state is reached it can radiate the heat away whilst mainitaining the same density.

I would think GW mechanisms vary from planet to planet simply because the atmospheres do. GW could still be huge, I dunno, but the atmosphere profile is different from ours, to say the least.
