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.
Which planet do you think is the hottest Why?
Venus is the hottest planet in the solar system. 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.
Which is the hottest planet answer?
In our solar system, Venus is the hottest planet. Though Mercury is the planet closest to the sun and therefore gets more direct sunlight, it’s not the hottest planet. Venus is the second planet near the sun, and it has a temperature that is kept at 462 degrees Celsius. Venus has a very dense carbon dioxide atmosphere.
Why the Venus is hotter than Mercury?
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.
Why Mercury is the hottest planet?
The hottest planet in the Solar System is none other than the second planet from the sun, Venus. While it is further away from the sun than Mercury, it has a dense atmosphere which traps the heat from the sun. This raises the overall sustained temperature on its surface above the levels found on Mercury.
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 place on earth?
Scientists still have to validate the reading of 130 degrees Fahrenheit on Sunday, the equivalent of 54 degrees Celsius. In the popular imagination, Death Valley in Southern California is the hottest place on earth.
Is it hot on Mars?
Overall, Mars is cold—its average global temperature is around -80 degrees Fahrenheit—and has a much thinner atmosphere than Earth. Because it has about a sixth of the pressure of Earth’s atmosphere, the planet doesn’t retain heat very long, causing temperatures to drop quickly.
Is it hot or cold on Mars?
Mars may look hot, but don’t let its color fool you — Mars is actually pretty cold! In orbit, Mars is about 50 million miles farther away from the Sun than Earth. That means it gets a lot less light and heat to keep it warm.
What is the 2nd coldest planet?
Venus is the hottest planet in the Solar System. Neptune has the coldest average temperature in the Solar System.

The Hottest And Coldest Planets Of Our Solar System.
| Rank | Planet and Pluto | Surface Temperature |
|---|---|---|
| 1 | Mercury | 800°F (430°C) during the day, -290°F (-180°C) at night |
| 2 | Venus | 880°F (471°C) |
| 3 | Earth | 61°F (16°C) |
| 4 | Mars | minus 20°F (-28°C) |
Do we have 2 suns?
The idea of a second sun in our solar system is not as bizarre as it might sound. Binary star systems (two stars orbiting the same center of mass) are quite common. In fact, Alpha Centauri, our solar system’s nearest neighbor, is a binary system.
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 brightest?
Venus is one of the brightest objects in the night sky. Venus is so bright because its thick clouds reflect most of the sunlight that reaches it (about 70%) back into space, and because it is the closest planet to Earth.
Is the sun a planet?
The Sun is a star. There are lots of stars, but the Sun is the closest one to Earth. It is the center of our solar system.
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.
