slide 37 and 38
What are two reasons Mercury lost most of its atmosphere? one reason is the little gas it has. The gas is trillions of sizes thinner then air on the surface of earth. The planets size also plays a part in why mercury has basically no atmosphere.
-mercury and earth distances from the sun-
mercury-60.108 million km
earth-147.7 million km
-distance between each other:190.62 million km-
-mercury and earths mass-
mercury-3.285 × 10^23 kg
earth-5.972 × 10^24 kg
how does not having an atmosphere affect the temp on mercury?since theirs basically no atmosphere it can not retain the heat.
