what are the two reasons Mercury lost most of it atmosphere.
cause it is to small to hold an atmosphere, lack of magnetic field.
compare how close Mercury & the Earth are to the sun.
Mercury 57.716 million km. Earth 151.21 million km.
compare how much mass Mercury & the Earth have.
earth 5.515 g/cm3. mercury 3.3 x 1023.
how does not having an atmosphere affect the temperature on Mercury.
During the day, temperatures on Mercury's surface can reach 800 degrees Fahrenheit (430 degrees Celsius). Because the planet has no atmosphere to retain that heat, nighttime temperatures on the surface can drop to minus 290 degrees Fahrenheit (minus 180 degrees Celsius)
