HD 85512 – a Solitary K-type Main-sequence Star

HD 85512 is a single K-type main-sequence star in the constellation Vela, located 37 light-years away. It is approximately one billion years older than the Sun. It has a very low chromospheric activity, only slightly higher than Tau Ceti. It is known to have one low-mass planet and to have long-term variability.

The star HD 85512 is approximately 36.9 light-years (11.3 pc) from our Solar System. HD 85512 has an apparent magnitude of 7.7 and an absolute magnitude of 7.4. It is 0.7 times more massive and 0.6 times larger than our Sun. The surface temperature is 4715 degrees Fahrenheit, and the spectral type is K5V.

Planetary system

The star HD 85512 is a Main Sequence Star. It is not part of the Vela constellation outline, but it is within its boundaries. The HD 85512 color is orange to red, based on the star’s spectral class (K5V). The star cannot be seen with the naked eye and must be viewed with a telescope. It is estimated to be 5.610 billion years old. ExoPlanet provided this information. At least one Extrasolar Planet is thought to be in orbit around HD 85512.

On August 19, 2011, HARPS identified a ≥3.6 Earth-mass planet “just inside” the habitable zone, together with the inner planets of e (or 82 G.) Eridani and HR 7722 c in Capricornus. These two comparison sets represent approximately a third of the subject’s distance from Earth. If the subject planet has more than 50% cloud coverage, it may be chilly enough to support liquid water. For a while, it was placed fifth in the Habitable Exoplanets Catalog for habitability, however, it was later listed as a false start as “too hot.”

HD 85512’s color and type are orange to red main sequence stars based on the star’s spectral classification of K5V. Based on the spectral type, we can estimate that the star’s surface temperature is in the range of 3,500 to 5,000K, according to Harvard University’s notes.

The radius of HD 85512 has been calculated to be 0.49 times that of the Sun. The radius of the Sun is 695,800km, hence the radius of the star is predicted to be 337, The solar mass of HD 85512 is 0.69 times that of our star, the Sun. The star is estimated to be 5.61 billion years old. To put in context, the Sun is believed to be about five billion years old and the Universe is about 13.8 billion years old.

The apparent magnitude of HD 85512 is 7.67, which is a measure of the star’s brightness as seen from Earth. Absolute Magnitude is the apparent magnitude of a star as seen from a distance of 10 parsecs (32.6 light-years). This presupposes that there are no obstacles between the object and the observer, such as dust clouds. To truly compare the brightness of a star, utilize Absolute Magnitude rather than Apparent Magnitude.
