It is the hottest planet in the solar system. So what makes Venus hotter than Mercury? Mercury doesn’t have any atmosphere, and atmosphere can hold and trap heat. … This thick atmosphere makes the surface of Venus hotter because the heat doesn’t escape back into space.
Why would Venus have hotter temperatures than mercury?
Venus has an atmosphere that is made of carbon dioxide and it also has clouds of acid inside the atmosphere, this thick atmosphere makes the surface of Venus hotter than Mercury and hotter than all the other planets which are found in our solar system because the heat does not escape back into space; this process is …
Which is hottest planet Mercury or Venus?
Mercury sure is hot, but Venus is hotter. Venus imaged by Magellan Image Credit: NASA/JPL Venus is much further from the Sun, orbiting at a distance of more than 108 million kilometers. Average temperature there is a hellish 735 Kelvin, or 462 degrees Celsius – hot enough to melt lead.
Why is Mercury not the hottest planet?
Because it is so close to the sun, it can be very hot. On its sunny side, Mercury can reach a scorching 800 degrees Fahrenheit! (But Mercury is not the hottest planet in the solar system. … On its dark side, Mercury gets very cold because it has almost no atmosphere to hold in heat and keep the surface warm.
Why is Venus the hottest planet despite not being the closest planet to the sun?
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. … The surface of Venus is extremely dry.
Is Venus hot or cold?
The average temperature on Venus is 864 degrees Fahrenheit (462 degrees Celsius). Temperature changes slightly traveling through the atmosphere, growing cooler farther away from the surface. Lead would melt on the surface of the planet, where the temperature is around 872 F (467 C).
What is the hottest planet on Earth?
Venus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet. The average temperatures of planets in our solar system are: Mercury – 800°F (430°C) during the day, -290°F (-180°C) at night. Venus – 880°F (471°C)
Why is Venus called Earth’s sister?
Venus is a terrestrial planet and is sometimes called Earth’s “sister planet” because of their similar size, mass, proximity to the Sun, and bulk composition. It is radically different from Earth in other respects.

Why is Venus so bright?
How best we see Venus depends on its position relative to Earth and the Sun. … Venus has an albedo of 0.7, which means that it reflects about 70 per cent of the sunlight that falls on it. So, that’s why Venus is shining so brightly at the moment, and it makes for wonderful viewing in the evening sky.
Can humans live Mercury?
Tough Place to Live
No evidence for life has been found on Mercury. Daytime Temperatures can reach 430 degrees Celsius (800 degrees Fahrenheit) and drop to -180 degrees Celsius (-290 degrees Fahrenheit) at night. It is unlikely life (as we know it) could survive on this planet.
Can humans visit Mercury?
No, Mercury has been visited by spacecraft from Earth, but no human has ever gone into orbit around Mercury, let alone stepped on the surface. … However, the temperatures on Mercury are much greater. During the daytime, the surface of Mercury at the equator rises to 700 Kelvin (427 degrees C).
What is the slowest planet?
Venus, which is floating higher each evening in twilight, low in the west, is the slowest-spinning body in the known universe.
How close is Venus to Earth today?
The distance of Venus from Earth is currently 257,825,833 kilometers, equivalent to 1.723459 Astronomical Units. Light takes 14 minutes and 20.0144 seconds to travel from Venus and arrive to us.

Why Venus is not habitable?
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.
