The average global temperature of the Earth's surface is about 15 degrees Celsius. This is a figure that is increasing due to climate change, although it makes our planet habitable. Venus is very hot, while Mars is a cold place, as indicated by its proximity and distance from the Sun. Space is a very cold place.Despite its proximity to the Sun, its temperature is colder than that of our planet. Science explains why.
The sun is a star with very high temperatures in all its layers. Nearly 15 million degrees at its core.This temperature varies depending on your condition. Layers ranging from the heart to the crown.The latter ranges between one and three million degrees.
These extreme temperatures are therefore essential for the processes that generate the light and heat that make life on Earth possible. Our planet receives heat from the Sun mainly through radiation, It is a process that begins when the sun emits energy in the form of electromagnetic radiation.
This is the scientific reason why it is cold in outer space even when it is close to the sun.
in the space, There is not enough atmosphere or material to retain or transfer heat effectively.Meanwhile, on Earth, the atmosphere retains and distributes heat, but in the vacuum of space, there are no molecules to do that. This explains why it is particularly cold in space.
Objects in space emit heat in the form of infrared radiation. Without an atmosphere to trap it, this radiation is lost into space, such as in satellites and space stations.s, which must be carefully managed to prevent them from getting too cold in the shade.
With no means of conducting or transmitting heat, and with thermal radiation being the primary form of heat loss, objects in space can experience very low temperatures.
The temperature in space can vary greatly.
In the shade, away from any heat source, the temperature can drop to about -270 °C (-454 °F), close to absolute zero. However, in direct sunlight, objects can reach temperatures of hundreds of degrees Celsius.
In addition, The temperature in interplanetary space (for example, between Earth and Mars) can be very low when it is far from any heat source.While the Moon's surface experiences temperatures ranging from approximately −173 °C (−279 °F) on the lunar night to 127 °C (260 °F) during the lunar day due to the lack of an atmosphere.
