What is Phobos day and night temperatures?

Phobos, one of Mars' moons, experiences extreme temperature variations due to its thin atmosphere. During the day, temperatures can reach around 25 degrees Celsius (77 degrees Fahrenheit), while at night, they can plummet to about -100 degrees Celsius (-148 degrees Fahrenheit). These fluctuations are a result of its close proximity to the Sun and lack of substantial atmospheric insulation.
