No, Venus is always very very hot.
No. Venus is very hot, with temperatures around 850 degrees Fahrenheit.
Venus is very hot with poisonous gases in the atmosphere, Mars is very cold with a low atmospheric pressure.
Venus doesn't get cold at night because it is so close to the sun.
No.
No.
Hard to say, as the distance from the star will also factor in, but in general, thin atmosphere would mean no insulation, it would be cold. Mars is a classic example of a planet having a thin atmosphere. It is extremely cold on Mars and has a small amount of carbon dioxide in it's atmosphere but is not in high enough concentration to warm the planet. Mercury has no atmosphere and it is hot and cold depending on which part of the planet is facing the Sun. Venus has a very dense amosphere and it is very hot, no matter which surface is facing the Sun.
The coldest temperature ever recorded on Venus is around -175 degrees Celsius (-283 degrees Fahrenheit) in its upper atmosphere layers. Venus has a very dense atmosphere that traps heat, leading to high surface temperatures despite the cold temperatures at higher altitudes.
cold
The surface of the planet Venus is not cold, but very very hot. The thick carbon dioxide atmosphere traps solar heat. So even though most of the Sun's radiation is reflected by the clouds around Venus, the surface temperature is as high as 460°C (860°F). The only cold places are high in the Venusian atmosphere on the night side of the planet. Temperatures high above the clouds (above 70 km in altitude) can get as low as -173°C (-280°F).
No. Venus is too hot for liquid water to exist.
We have two such planets in the solar system, which are Mercury and Venus. There are also several other planets that have no oceans but which are cold.
