38 Leonis Minoris is a binary star^[3] system in the northern constellation of Leo Minor. It shines with a combined light of apparent magnitude 5.84,^[2] which indicates it a dimly visible to the naked eye under good viewing conditions. An annual parallax shift of 19.8 mas provides a distance estimate of around 165 light years. It has a relatively high proper motion, traversing the celestial sphere at a rate of 0.226 arcseconds per year,^[10] and is moving away from the Sun with a radial velocity of +31 km/s.^[4]

This is a single-lined spectroscopic binary^[3] with an orbital period of 7.8 days and a low eccentricity of 0.023 – nearly circular.^[5] The visible component has a stellar classification of G0 IV,^[3] matching a G-type subgiant star that is exhausting the hydrogen at its core and evolving into a giant. It is about two^[7] billion years old with 1.68^[6] times the mass of the Sun and is spinning with a projected rotational velocity of 14.5 km/s.^[5] The star has a higher than solar abundance of iron in its spectrum.^[7] It is radiating 11^[2] times the Sun's luminosity from its photosphere at an effective temperature of 6,106 K.^[7]
