Why can the moon be far hotter than the Death Valley and far colder than the Antarctica since its distance to the sun is similar to?

the distance between the earth and the sun

    The moon has no air or water to moderate the temperature.

    Because it has no atmosphere. Nothing to hold the heat in, or to allow it

    to cool off.

    It doesn't have an atmosphere to moderate the temperature.

    The Moon has little or no Atmosphere

     It means that it gets the full Radiation of the Sun with no protection, no clouds or rain 

    Anywhere on the Moon can be in the dark or in Sunlight

    So it is more extreme

    So just think of poor Mercury

    The Moon only rotates once every 27 days.   A location on the Moon stays in sunlight much longer and so gets much warmer.   A location not in sunlight is dark much longer so it cools more.

    Also, since the Moon doesn't have an atmosphere,  there is no convection to transfer heat from the equator to the poles. Antarctica gets some heat through convection of the Earth's atmosphere so it is warmer then the Moon's poles. Craters near the poles of the Moon may never see any sunlight at all and get no heat from convection so they get quite cold indeed.

    It doesn’t have an atmosphere to temper and slow the rate of solar energy absorption, or the heat radiation from it’s surface.

    The average temperature of the Moon is about 30 C colder than the Earth, because the Earth gets about 30 C worth of greenhouse effect (and going up all the time).

    Because it has no atmosphere. The earth's atmosphere partially shields the surface from direct radiation, also heating the air around you instead of the surface only. Some of that air remains heated over night (even long polar nights) so that the surface doesn't get as cold.

    Gravity holds atmosphere, which act as green house.

    Air.  The atmosphere of Earth is a living system.
