Question

What is the coldest planet? And what is the hottest planet?

Answer 1

In order to find the hottest and the coldest planet in the solar system, we have to first discuss about what is solar system and then make the list of all the planets of the solar system and their characteristics, thereafter we will be able to find out about hottest and coldest planet.

Complete step-by-step solution:
In the question given above we will first discuss what is the solar system?
Solar system is the collection of the eight planets and their moons in orbit revolving around the sun, together with smaller bodies in the form of asteroids, meteoroids, and comets.
The eight planets present in the solar system are as follows:
1. Mercury
2. Venus
3. Earth
4. Mars
5. Jupiter
6. Saturn
7. Uranus
8. Neptune
Now let us discuss about the temperature of the planets in the solar system
We know that mercury is the nearest planet to the sun so it should be the hottest planet but it is not so Venus is the hottest planet in the solar system because mercury does not consist of atmosphere
Let us now discuss of the characteristics of Venus:
Venus is the second nearest planet to the sun and it is the brightest planet in the solar system. The temperature of Venus’s surface is approximately equal to 880 degrees Fahrenheit. This temperature is 90 times as that of earth. The atmosphere of Venus consists of carbon dioxide and clouds made up of sulfuric acid.
The coldest planet in the solar system is Uranus which is the seventh planet in the solar system. Its average temperature is -195 degree centigrade also it is the third largest planet in the solar system. It is the ice giant, most of its mass is made of dense icy fluids like water ammonia and methane. The atmosphere is mostly made of molecular hydrogen and atomic helium.

Note: In the question above remember that mercury being the nearest planet to the sun still is not the hottest planet, Venus the hottest planet and same is the case in coldest planet Neptune being the farthest planet is still not the coldest one Uranus the eighth planet is the coldest one.
