Mercury because one side of it is always turned towards the Sun.
The side of the Earth facing the Sun would get very hot and the side of the Earth in dark would get very cold.
Answer : The planet Mercury does not rotate on an axis relative to the Sun. Consequently, the side facing the Sun is very hot while the back of the planet away from the Sun, never receiving warming sunlight is relatively cold.Or so it was thought, it has now been pr oven that Mercury does rotate, albeit very slowly. It is close to the sun and lacks a protective atmosphere
It is the closest to the sun so the side that faces the Sun gets very hot. It has no atmosphere to retain the heat, so when the side is facing away from the sun, the temperature drops drastically and it becomes very cold.
the sun, Pluto is a very cold dwarf planet, which is very small and was just recently proven a dwarf planet.
It is very hot on the side that is facing the sun and very cold on the side that is not facing the sun. This is because Mars has a very thin atmosphere.
If the Earth stopped rotating, there would be significant impacts. The side facing the Sun would become very hot while the side facing away would become very cold. This temperature difference could lead to extreme weather patterns and have disastrous consequences for life on Earth.
Mercury has no Atmosphere and is very hot facing the Sun and very Cold facing away from the Sun. Not conducive to life as we know it.
The closest planet to the sun is Mercury. Mercury is not the hottest planet because it has no atmosphere to hold onto that heat, so it quickly radiates that heat back into space. As a result the side of Mercury facing the sun is quite hot while the side facing away is cold. Venus, the second planet from the sun, is the hottest as its dense carbon dioxide atmosphere is very good at retaining heat.
Mercury because one side of it is always turned towards the Sun.
The planet is very hot on the side facing the sun, up to 800°F (425°C), but in the near vacuum there, it could be dealt with by shielding and cooling. With Mercury's "day" being 58.6 of our days, astronauts could spend weeks on the "cold" side facing away from the Sun, or on the more-temperate boundary zones.
The side of the Earth facing the Sun would get very hot and the side of the Earth in dark would get very cold.
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.
Well, assuming the Earth rotated in such a way that one side was always facing the sun and the opposite side were always facing away from it, like Venus (maybe it was Mercury), then Earth could not support life because the side facing the sun would be very hot, and the other side would be very cold, like Venus, the side always facing the sun is around 900 degrees F, and the cold side is around -280 or -300 degrees F.
Rocky with very little atmosphere. It is the closest planet to the Sun and the side facing the Sun can get to 450 degrees Celsius, 840 Fahrenheit (hot enough to melt lead). The side that is facing away from the Sun (their nights last about a quarter of an Earth year) will get as cold as -170 Celsius, -275 Fahrenheit.
cold and very hot....
I think the planet you are thinking of is Mercury.
