Asteroid discovered in 1898
I believe the answer is:
eros
'asteroid discovered in 1898' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for eros that I've seen before include "Roman god of love, Cupid" , "Greek god of love - see statue in Piccadilly" , "Cupid, to the Greeks" , "asteroid four hundred and thirty three" , "Love-god's statue in Piccadilly" .)
