HD 93833

HD 93833 (HR 4233; 73 G. Sextantis) is a solitary star located in the equatorial constellation Sextans. It is faintly visible to the naked eye as an orange-hued point of light with an apparent magnitude of 5.84. Gaia DR2 parallax measurements imply a distance of 345 light-years and it receding with a heliocentric radial velocity of $$. At its current distance, HD 93833's brightness is diminished by an interstellar extinction of 0.18 magnitudes and it has an absolute magnitude of +0.76.

HD 93833 has a stellar classification of K0 III, indicating that it is an evolved K-type giant star that has exhausted hydrogen at its core and left the main sequence. It is currently a red clump star that is on the horizontal branch—fusing helium at its core. It has 1.4 times the mass of the Sun but at the age of 5.5 billion years, it has expanded to 10.7 times the radius of the Sun. It radiates 60.4 times the luminosity of the Sun from its photosphere at an effective temperature of $$. HD 93833 is slightly metal deficient with an iron abundance of [Fe/H] = −0.11 or 77.6% of the Sun's abundance.
