How hot would Venus be without the greenhouse effect?

Planets with low albedo absorb more sunlight, leading to hotter temperatures. Venus would be 510°C colder without greenhouse effect.

What is the temperature of a habitable planet?

The advanced life that we know about depends upon water, so one condition for the habitable zone is that water can exist in liquid form, so this requires a temperature range between 0°C and 100°C.

Was Venus habitable at some point?

To date, no definitive proof has been found of past or present life on Venus. With extreme surface temperatures reaching nearly 735 K (462 °C; 863 °F) and an atmospheric pressure 90 times that of Earth, the conditions on Venus make water-based life as we know it unlikely on the surface of the planet.

How hot would Venus be if it had Earth’s atmosphere?

According to calculations, maximum temperatures would be just around 35 °C (95 °F), given an Earth-like atmosphere.

How hot will Venus get?

Although Venus is not the planet closest to the sun, its dense atmosphere traps heat in a runaway version of the greenhouse effect that warms Earth. As a result, temperatures on Venus reach 880 degrees Fahrenheit (471 degrees Celsius), which is more than hot enough to melt lead.

How is Venus the hottest planet?

Even though Mercury is closer to the Sun, Venus is the hottest planet in our solar system. Its thick atmosphere is full of the greenhouse gas carbon dioxide, and it has clouds of sulfuric acid. The atmosphere traps heat, making it feel like a furnace on the surface. It’s so hot on Venus, the metal lead would melt.

What is the temperature of Venus?

It appears that the surface temperature ranges from about 820 degrees to nearly 900 degrees F. The average surface temperature is 847 degrees F., hot enough to melt lead. No wonder the ocean basins are “dry”.

What temperature range is good for life the temperature range that a planet must have in able for us to survive?

Life seems limited to a temperature range of minus 15oC to 115oC. In this range, liquid water can still exist under certain conditions. At about 125oC, protein and carbohydrate molecules and genetic material (e.g., DNA and RNA) start to break apart. Also, high temperatures quickly evaporate water.

How hot is Venus?

about 900 degrees Fahrenheit
It’s the hottest planet in our solar system, even though Mercury is closer to the Sun. Surface temperatures on Venus are about 900 degrees Fahrenheit (475 degrees Celsius) – hot enough to melt lead. The surface is a rusty color and it’s peppered with intensely crunched mountains and thousands of large volcanoes.

What if Venus was further from the Sun?

Beyond Jupiter’s orbit, temperatures on Venus would approach –280 F (–173 C) and likely even colder near the farthest edges of our solar system. Thus, even Venus can become chillingly cold if located far enough away from the Sun.

Would the Earth be habitable at Venus’ distance to the Sun?

KarenRei’s answer is very good as there is a significant degree of uncertainty, that said, I think the answer to this question is a clear no, the Earth would not be habitable at Venus’ distance to the Sun. Not unless you’re a waterbear living in a very deep cave. Venus’ average distance to the sun is .722 AU. Source.

Did Venus once have a shallow liquid-water ocean?

Credit: NASA. Venus may have had a shallow liquid-water ocean and habitable surface temperatures for up to 2 billion years of its early history, according to computer modeling of the planet’s ancient climate by scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York.

What happened to Venus’s atmosphere?

The simulations suggest that Venus went through a rapid cooling phase a few billion years after it formed. Then, the atmosphere would have been full of carbon dioxide. If Venus evolved similarly to Earth, that carbon dioxide would have come down from the atmosphere, drawn by silicates, and become trapped in the surface.

What was the climate like on Venus in ancient times?

That means an ancient Venus with an Earth-like atmosphere could have had the same rotation rate it has today. Another factor that impacts a planet’s climate is topography. The GISS team postulated ancient Venus had more dry land overall than Earth, especially in the tropics.
