  Jupiter-family Comet D/1770 L1 (Lexell) was the first discovered Near-Earth
Object (NEO), and passed the Earth on 1770 Jul 1 at a recorded distance of
0.015 au. The comet was subsequently lost due to unfavorable observing
circumstances during its next apparition followed by a close encounter with
Jupiter in 1779. Since then, the fate of D/Lexell has attracted interest from
the scientific community, and now we revisit this long-standing question. We
investigate the dynamical evolution of D/Lexell based on a set of orbits
recalculated using the observations made by Charles Messier, the comet's
discoverer, and find that there is a $98\%$ chance that D/Lexell remains in the
Solar System by the year of 2000. This finding remains valid even if a moderate
non-gravitational effect is imposed. Messier's observations also suggest that
the comet is one of the largest known near-Earth comets, with a nucleus of
$\gtrsim 10$ km in diameter. This implies that the comet should have been
detected by contemporary NEO surveys regardless of its activity level if it has
remained in the inner Solar System. We identify asteroid 2010 JL$_{33}$ as a
possible descendant of D/Lexell, with a $0.8\%$ probability of chance
alignment, but a direct orbital linkage of the two bodies has not been
successfully accomplished. We also use the recalculated orbit to investigate
the meteors potentially originating from D/Lexell. While no associated meteors
have been unambiguously detected, we show that meteor observations can be used
to better constrain the orbit of D/Lexell despite the comet being long lost.
