| Oct 15, 2022 at 19:49 | comment | added | Mazura | "Due to the lack of the intrinsic magnetic field on Venus, the solar wind penetrates relatively deep into the planetary exosphere and causes substantial atmosphere loss." +1... "work using NASA's MAVEN orbiter found that much the planet's atmosphere was stripped away by the solar wind—charged particles streaming from the sun—perhaps just 500 million years after Mars formed." -1... "it lost its atmosphere to space after losing its magnetic field, its small size prevented it from holding its atmosphere" -1/+1... TLDR Because Mars has neither the mass nor a field, and Venus almost has both. | |

| Oct 15, 2022 at 2:47 | comment | added | Seth Robertson | Great answer, but I believe the paragraph starting with "According to table 5" has some typos. I believe you dropped some zeros since the numbers as written were .3 at 100k, .1 at 200K, .5 at 300K, .2 at 400K, and suddenly down to .007 at 500K. | |
