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)
Which is hotter Mercury or Venus?
The carbon dioxide traps most of the heat from the Sun. The cloud layers also act as a blanket. The result is a “runaway greenhouse effect” that has caused the planet’s temperature to soar to 465°C, hot enough to melt lead. This means that Venus is even hotter than Mercury.

What is the hottest planet in the atmosphere?
Even though Venus isn’t the closest planet to the Sun, it is still the hottest. It has a thick atmosphere full of the greenhouse gas carbon dioxide and clouds made of sulfuric acid. The atmosphere traps heat and keeps Venus toasty warm.
Why is Mercury not the hottest?
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.
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).
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.
What planet is cold?
The short answer is that Neptune has the coldest overall average temperature and Uranus has the coldest temperature recorded. The long answer is that once upon a time the answer to this question was simple. Pluto was the planet furthest away from the Sun and also the coldest.
What is the coldest rocky planet?
With a temperature of -357 degrees Fahrenheit, Uranus is the coldest planet in the solar system. The atmosphere is made up of methane, hydrogen and helium – the methane giving it its green look. Most of the mass of Uranus is made up of water, methane and ammonia ice.
How cold is the coldest planet?
Neptune is the coldest planet in the universe and sees temperatures of below -210 degrees Celsius.
How close is Venus to Earth today?
The distance of Venus from Earth is currently 257,817,325 kilometers, equivalent to 1.723402 Astronomical Units. Light takes 14 minutes and 19.9860 seconds to travel from Venus and arrive to us.

Is Venus visible from Earth?
Venus. You can’t miss Venus. You’ve likely already noticed the planet in the western sky just after sunset. … Like Mercury, its orbit is closer to the sun than Earth (these are referred to as the “inferior” planets), so Venus is visible before and after sunrise, depending on where it is in its orbit.
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 planet is closest to the sun?
