Major name in astronomy (4)
I believe the answer is:
ursa
'major name' is the definition.
(I've seen this in another clue)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for ursa that I've seen before include "It's both major anf minor overhead" , "Bear (constellation)" , "- Major, - Minor, prominent constellations" , "__ Minor, the Little Bear" , "The Major one is the Plough" .)
