  Comet P/2019 LD2 has orbital elements currently resembling those of a Jupiter
Trojan, and therefore superficially appears to represent a unique opportunity
to study the volatile content and active behavior of a member of this
population for the first time. However, numerical integrations show that it was
previously a Centaur before reaching its current Jupiter Trojan-like orbit in
2018 July, and is expected to return to being a Centaur in 2028 February,
before eventually becoming a Jupiter-family comet in 2063 February. The case of
P/2019 LD2 highlights the need for mechanisms to quickly and reliably
dynamically classify small solar system bodies discovered in current and
upcoming wide-field surveys.
