Respuesta :

1. The hottest planet would be the mercury.
The closer a planet to the sun, the hottest the temperature of that planet will become. During the day, the temperature in mercury could obtain 427 degree celcius which could even melt several forms of metals.

2. The coldest planet would be the Neptune
Since now pluto is no longer considered a planet, the planet that located the furthest from the sun and the coldest one would be neptune, which had the average temperature of -213 degree celcius

3. the answer is Mars.
Due to this close similarties, we already made an effort to start and develop human civilization on that planet (which is led by a famous figure Elon Musk)

5. The answer is jupiter
Gravitational attraction is directly correlated to the mass of the planet. When it's measured, jupiter gravitational pull is about 2.4 times larger compared to the earth's

6. The answer mercury
Mercury is currently the smallest planet since pluto now out of the equation. When its measured, Mercury gravirtational pulll is about 0.383 times compared to the earth's

7. The answer is venus
Venus has the most similar size with the planet earth. When it's measured, Venus gravitational pull is about 0.91 times compared to the earth's

8. the answer is mars, jupiter, and Earth
But from the three planets, the air composition that humans can take without having any additional device is only Earth,  the others have too much Carbon dioxide composition for humans to handle

9.The answer is Mars
like mentioned above, because of the smilarties in gas, water, and temperature, Mars probably the next livable planet for humans beside the planet earth

10. The answer is Earth and Mars.
At first, we thought that Earth is the only one that has it. But in 2015, NASA found that Mars has some water flow even though it only ran intermittently.

11. The answer is Mars.
The only problem is the amount. Mars currently does not have enough flowing water to sustain humans life and it has too much composition of air that will be dangerous for humans

12.  Again, the answer is Mars
For all the reasons that mentioned above

13. The answer is Mars.
In order to live, what we need is food, water, air, and the temperature that do not kill us. Mars has the all of those things, eventhough the amount might not be as ideal as the earth. Currently, besides NASA, private sectors such as Space X has came in to try and solve this problems for us.

Further explanation

Planets are members of celestial bodies that have several variations with certain shapes and sizes on planets. Planets are divided into 8 namely Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune that have variations with certain size shapes on each planet. The following is an explanation of the 8 planets:

1. Mercury

Planet Mercury is the closest planet to the sun which has a distance of about 58 million kilometers from the sun. Mercury is the smallest planet among all the other planets. Mercury has only 4,862 km, on the surface mercury provides hot and dry energy. Mercury has a temperature of 427 ° C during the day and has a temperature of 184 ° C at night.

2. Venus

Planet Venus is the second planet closest to the sun in the solar system which has a distance of about 108 million kilometers. On the surface of the planet, Mercury is surrounded by thick clouds of carbon dioxide so it will be difficult to see.

3. Earth

On this earth, there is an atmosphere that protects and perfects organic chemicals to protect the sun's layer. So that this planet is the only planet in the solar system that can support the existence of life and earth, including the third planet in the order of the solar system.

Earth is the most dynamic planet that can recycle itself with the temperature and pressure of the earth's surface allowing for water and can be used as liquid, solid or gas.

4. Mars

Mars is the second planet from the sun which is smaller than Earth. The results of research on the surface of Mars found the presence of liquid water in the past before researching so that Mars is almost the same as the earth.

5. Jupiter

Jupiter is the fifth planet in the order of the solar system. Jupiter is the largest planet among all the other planets. Jupiter also has an atmospheric layer composed of hydrogen and helium and clouds of ammonia and ice crystals.

6. Saturn

Saturn is the sixth planet in the order of members of the solar system. The planet Saturn contains a lot of helium gas and hydrogen, causing the planet's density so that the planet can float on water.

7. Uranus

Uranus is the seventh planet in the order of members of the solar system. The Uranus planet is very different from the other planets because one of the poles of the Uranus planet faces the sun and rotates on an axis that is in the same plane as the circular plane around the sun.

8. Neptune

Neptune is a planet that has hurricane winds, so it is called the windiest planet in the solar system. Neptune planet has similarities with Uranus which has an atmosphere consisting of helium and hydrogen and has the same methane gas as the planet, Neptune.
