HD 145377 is a star in the southern constellation Scorpius. It has an apparent visual magnitude of 8.10 and can be viewed with a small telescope. The star is located at a distance of 175 light years from the Sun based on parallax, and it is drifting further away with a radial velocity of +11.6. The absolute magnitude of this star is 4.31, indicating it would be visible to the naked eye if it were at a distance of 10 parsecs.

This is an ordinary G-type main-sequence star with a stellar classification of G3V, which indicates it is undergoing core hydrogen fusion. It is 5–12% larger and 13% more massive than the Sun. It may be younger than the Sun, with age estimates in the range of 1–3 billion years. The star is spinning with a projected rotational velocity of 3.85 km/s, giving it a rotation period of ~12 days. The abundance of elements more massive than helium – what astronomers term the star's metallicity – is ~31% higher than in the Sun. The star is radiating around 43% to 56% of the luminosity of the Sun from its photosphere at an effective temperature of 6,046 K.
