5 Leonis Minoris (5 LMi), commonly referred to as HD 75332, is a yellow-white star in the northern constellation of Lynx, close to the border with Cancer.

This is an ordinary F-type main-sequence star with the stellar classification F7V, meaning it is fusing hydrogen into helium at its core to generate energy.

[6] Compared to the Sun, the star is overall slightly more enriched in elements heavier than hydrogen and helium, with a metallicity measured at [M/H] = 0.05±0.03 dex (i.e., 12±8 % richer).

[3] It is about 120 times richer in lithium ([Li/H]=2.08±0.05 dex), and also substantially enhanced in calcium, scandium, titanium, iron, and nickel, but somewhat poor in nitrogen (10−0.11 ≈ 78% the solar abundance).

[3] In 2019, the star was discovered to exhibit cyclical chromospheric activity, measured by the Mount Wilson S-index, with a period of approximately 180 days.
