Q. What was the first planet in our galaxy?
The order of the planets in the solar system, starting nearest the sun and working outward is the following: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and then the possible Planet Nine. If you insist on including Pluto, it would come after Neptune on the list.
Q. What is the name of the coldest planet?
The seventh planet from the sun, Uranus has the coldest atmosphere of any of the planets in the solar system, even though it is not the most distant.
Q. Why is Venus the hottest planet?
Venus is so hot because it is surrounded by a very thick atmosphere which is about 100 times more massive than our atmosphere here on Earth. As sunlight passes through the atmosphere, it heats up the surface of Venus.

Q. Is there a 9th planet?

Q. Is Venus closest to Sun?
Venus is the second planet from the Sun and Earth’s closest planetary neighbor. Even though Mercury is closer to the Sun, Venus is the hottest planet in our solar system.
Q. Why Venus is not habitable?
As a result of Jupiter – the largest planet in our solar system – moving closer and then away from the sun in its early formation, the planet’s vast gravitational pull effectively killed off Venus’ potentially Earth-like environment, the authors of a study published in the Planetary Science Journal found.
Q. How far is Venus from Earth today?
221,098,353 kilometers
Q. 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).
Q. Does Venus have ice?
Venus is too hot to have any type of ice on it. The surface of Venus is covered by its thick atmosphere of carbon dioxide. Water ice is found where the temperatures are below the freezing point of water and there is enough precipitation for snow or ice crystals to fall or there is water that can freeze.
