All of us have been listening to concerning the phrases planetary safety and planetary protection being utilized by the official in a distinct but related method. However do you really know what they imply and the way researchers and astronomers used these phrases?
Each of the phrases embody “planetary” so their meanings and behaviours have to be comparable. Nonetheless, that is the one resemblance between them; their distinct tasks are what set them aside.
