# Does astronomical observing “count” as remote sensing?

I have long considered astronomical observing as a form of remote sensing, though quite different than typical remote sensing in that many objects observed are not resolved.

I am wondering, though, if the formal definitions of remote sensing include or exclude astronomical observing (and specifically, observing things outside the solar system)? And/or are there any resources that can be pointed to that either do or don't call astronomical observing remote sensing?

• What is remote sensing? Or better in what it differs from remote observation? And to what remote refer to here? Space, time? Both? If I stick to the first definition I have found than not. Is quite "technological" and it assume an active action by the observer,e.g. irradiatimg an object and look for its response. – Alchimista Jan 25 '19 at 9:52
