I want to know the answer to the following question:
What is the only object identified with Neptune's trailing L5 Lagrangian point?
All the background I'm provided with is that "Neptune has a number of known trojan objects occupying both the Sun–Neptune L4 and L5 Lagrangian points—gravitationally stable regions leading and trailing Neptune in its orbit, respectively.". Is that enough to answer the question?
Answer: no
