'our rock' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'surface temperature affected heart' is the wordplay.
'surface' becomes 'plane' (I've seen this before).
'temperature' becomes 't' (abbreviation).
'affected' indicates an anagram.
'heart' with letters rearranged gives 'earth'.
'plane'+'t'+'earth'='PLANET EARTH'

'of' acts as a link.
