40 Leonis Minoris (40 LMi) is a white hued star located in the northern constellation Leo Minor.

It is rarely called 14 H. Leonis Minoris, which is the designation given by Polis astronomer Johann Hevelius.

The object is located relatively close at a distance of 154 light years based on Gaia DR3 parallax measurements[1] but is receding with a somewhat constrained heliocentric radial velocity of 10 km/s.

[15] 40 LMi is a chemically peculiar A-type main-sequence star with a stellar classification of A4 Vn.

[9] It radiates 14.3 times the luminosity of the Sun[3] from its photosphere at an effective temperature of 7,834 K.[10] The star is estimated to be 207 million years old, having completed 54.6% of its main sequence lifetime.
