HD 196761
Encyclopedia
HD 196761 is a main sequence
dwarf star
in the constellation Capricornus
and is located about 47 light years from the Solar System
. It has a stellar classification
of G8V and is about 88% of the radius of the Sun. Compared to the Sun
, this star has about half the proportion of elements other than hydrogen and helium.
The space velocity components of this star are U = −59, V = 20 and W = 4 km/s. It is following an orbit through the Milky Way
that has an eccentricity of 0.18, bringing it as close as 24.27 kly and as distant as 34.6 kly from the galactic core. The inclination
of this orbit will carry HD 196761 no more than 0.65 kly from the plane of the galactic disk.
Main sequence
The main sequence is a continuous and distinctive band of stars that appears on plots of stellar color versus brightness. These color-magnitude plots are known as Hertzsprung–Russell diagrams after their co-developers, Ejnar Hertzsprung and Henry Norris Russell...

Dwarf star
The term dwarf star refers to a variety of distinct classes of stars.* Dwarf star alone generally refers to any main sequence star, a star of luminosity class V.** Red dwarfs are low-mass main sequence stars....

Capricornus
Capricornus is one of the constellations of the zodiac; it is often called Capricorn, especially when referring to the corresponding astrological sign. Its name is Latin for "horned male goat" or "goat horn", and it is commonly represented in the form of a sea-goat: a mythical creature that is half...

Solar System
The Solar System consists of the Sun and the astronomical objects gravitationally bound in orbit around it, all of which formed from the collapse of a giant molecular cloud approximately 4.6 billion years ago. The vast majority of the system's mass is in the Sun...

Stellar classification
In astronomy, stellar classification is a classification of stars based on their spectral characteristics. The spectral class of a star is a designated class of a star describing the ionization of its chromosphere, what atomic excitations are most prominent in the light, giving an objective measure...
