This question to help with a personal fictional work: Would it be possible 
for a meteor/comet the size of earth to fly across the cosmos over a long 
period of time avoiding major collisions but slowly eroding until arriving 
at earth passing through the atmosphere and being the size of a pebble? I 
can expand on this if required. Thanks for your consideration.
