How big would a ball of frozen water need to be to last one orbit? How would atmospheric drag effect the ball of water?

    $\begingroup$ This is a "how long is a piece of string" question. Depending on various factors, the ball would last something between a second and forever. $\endgroup$ – James K Nov 21 '18 at 23:10

    $\begingroup$ Neat info in ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19770027123.pdf especially near 3.2.3.1.6 and figure27. Would take some work to integrate that over a sphere of a specific size though. $\endgroup$ – BowlOfRed Nov 22 '18 at 0:19
  • $\begingroup$ @BowlOfRed That's quite a nice report and set of experiments, great find! $\endgroup$ – uhoh Nov 22 '18 at 13:31

    $\begingroup$ Please add in the info suggested by your last question on this, such as how you will prevent it sublimating. You'll also need to add size, orbit height and eccentricity etc. Way too broad currently. $\endgroup$ – Rory Alsop Nov 22 '18 at 17:04

    $\begingroup$ No. You need to add info onto the question. Not just a link to another post. $\endgroup$ – Rory Alsop Nov 23 '18 at 11:03

Simply put. It all depends on the balance of an objects straight line speed orbiting the planet and gravity. The further away the object is from earth the slower the speed requirement for this balance is. Great question by the way.
