# How cold is outer space near Earth?

## How cold is outer space near Earth?

The average temperature of outer space near Earth is 283.32 kelvins (10.17 degrees Celsius or 50.3 degrees Fahrenheit). In empty, interstellar space, the temperature is just 3 kelvins, not much above absolute zero, which is the coldest anything can ever get.

## How cold is space exactly?

This is known as the cosmic microwave background (CMB) and it has a uniform temperature of 2.7 K (-45⁰F/-270⁰C). As 0 K is absolute zero this is a temperature just 2.725 degrees above absolute zero.

How hot can it get in space?

On the Sun-facing side of the ISS, temperatures can rise up to 250 degrees Fahrenheit. Conversely, on the dark side of the space station, temperatures can drop as low as minus 250 degrees Fahrenheit. This is why the space stations use solar panels to keep an even temperature for the station’s astronauts.

### How cold is space in C?

(-270.45 Celsius, -454.81 Fahrenheit)
As you probably know, space is already very, very cold — roughly 2.7 Kelvin (-270.45 Celsius, -454.81 Fahrenheit). This is mostly due to a lack of atmosphere and the vacuum-like nature of space — with very few molecules to energetically bounce around, there can be no heat.

### How fast would you freeze in space?

90 seconds after exposure, you’ll die from asphyxiation. It’s also very cold in space. You’ll eventually freeze solid. Depending on where you are in space, this will take 12-26 hours, but if you’re close to a star, you’ll be burnt to a crisp instead.

How cold is Moon?

The average temperature on the Moon (at the equator and mid latitudes) varies from -298 degrees Fahrenheit (-183 degrees Celsius), at night, to 224 degrees Fahrenheit (106 degrees Celsius) during the day.

#### How cold is it on Pluto?

-387°F
It’s about 3.6 billion miles away from the Sun, and it has a thin atmosphere composed mostly of nitrogen, methane, and carbon monoxide. On average, Pluto’s temperature is -387°F (-232°C), making it too cold to sustain life.
