I am up when you are not. I am cold when you are hot. What am I?

Common Wrong Answers

The sun

The sun is active during the day when people are typically awake and warm, making it the opposite of the riddle's description.

A snowman

A snowman can be cold regardless of the time of day and does not have a direct relationship with being up when people are not.

A star

While stars are visible at night, they do not specifically represent being 'up' when people are not, as they are always in the sky regardless of human activity.
