Reply to comment by LaunchTransient in Mars was once covered by 300-meter deep oceans, study shows by magenta_placenta
To nitpick; Earth is about 70% the distance Mars is - it gets roughly twice as much sunlight rather than four times as much. Venus in turn gets about twice as much as Earth and four times as much as Mars.
