HD 126053

HD 126053 is a star located in the constellation Virgo. It is a solar analog, meaning its physical properties are similar to the Sun, although it is metal-poor. Here are some key details about HD 126053:

Distance: Approximately 57 light years from Earth.

Apparent Magnitude: 6.25, which makes it faintly visible to the naked eye under dark suburban or rural skies.

Spectral Type: G1 V, indicating it is a yellow dwarf star.

Temperature: About 5,722 K.

Mass: 0.89 times the mass of the Sun.

Radius: 0.93 times the radius of the Sun.

Luminosity: 0.83 times the luminosity of the Sun.

Age: Estimated to be around 5.49 billion years old.

In 2012, a brown dwarf was discovered orbiting HD 126053 at a distance of 2630 AU. This brown dwarf, designated as HD 126053 B, is a T-type brown dwarf with a spectral type of T8p, indicating a low temperature.

HD 2151 - Totalement dominée

En lien direct avec la Terre

Beta Hydri (β Hyi, β Hydri) is a star in the southern circumpolar constellation of Hydrus. (Note that Hydrus is not the same as Hydra.) With an apparent visual magnitude of 2.8,[2] this is the brightest star in the constellation. Based upon parallax measurements the distance to this star is about 24.33 light-years (7.46 parsecs). This star has about 113% of the mass of the Sun and 184% of the Sun's radius, with more than three times the Sun's luminosity

HD 211415 - Partiellement dominée

is a double star in the constellation Grus. With an apparent visual magnitude of 5.33, it is visible to the naked eye. The annual parallax shift is 72.54 mas, which yields a distance estimate of 45 light years. It has a relatively high proper motion, traversing the celestial sphere at the rate of 93.4 mas per year,[12] and is moving closer to the Sun with a radial velocity of −13 km/s.[5]

HD 200525 - Partiellement dominée

HD 200525 is a white to yellow subgiant star in the constellation of Pavo. It can be seen in the southern hemisphere night sky. HD 200525 distance from Earth is 64.47 light years away.

HD 61606 - Totalement dominée

HD 61606 is a star system located approximately 46 light years from the Sun and consists of four stars. Currently, no exoplanets are identified in this system.

Conclusions: c'est la planète [2] que les Orions ont "volé" à leur anciens amis de voyage les Tauriens/Ebens lorsque la leur est devenu invivable. Il s'agit donc du monde d'origine des Tauriens.

HD 50281 - Planète adaptée

is a star located in the equatorial constellation of Monoceros. It has an apparent visual magnitude of 6.58 and is approximately 28.5 light years away from the Sun. The star is an orange hue and has a stellar classification of K3.V, indicating it is a K-type main sequence star. It is nearly two billion years old and has a mass of about 79% of the Sun’s mass, with a radius of about 73% of the Sun’s radius. The star emits about 22.5% of the luminosity of the Sun and has an effective temperature of around 4,712 K.

HD 10700 - Partiellement dominée

Location: HD10700 is a G8V star, located approximately 3.65 parsecs (12 light-years) away from the Sun in the constellation Cetus. Planetary System: At least five potentially terrestrial planet candidates have been discovered orbiting HD10700, with minimum masses ranging from 2 to 6.7 Earth masses. Chemical Composition: Abundance analysis suggests that HD10700 has a higher Mg/Si ratio (1.78) compared to the Sun (about 1.2). This could imply a different mineralogical makeup for planets around HD10700, potentially leading to oversaturation of MgO. Habitable Zone: Depending on atmospheric properties, up to two planets (e and f) may be located within the habitable zone of HD10700 at its current estimated age of 7.63 billion years. Stellar Activity: The star’s radial velocity (RV) measurements have been affected by stellar activity, which can impact exoplanet detection. A recent study used a convolutional neural network to mitigate this effect and achieve detection thresholds as low as 0.5 m/s in semi-amplitude for planets with periods ranging from 10 to 300 days.

C'est une naine orange de type spectral K1 V2. Elle a une taille de 80 %5 et une luminosité de 37 % celle du Soleil.

HD 224930 - Totalement dominée

85 Pegasi is a multiple star system 39.5 light years away[2] in the constellation of Pegasus. The primary component is sixth magnitude 85 Pegasi A, which is a yellow dwarf like the Sun. The secondary component, 85 Pegasi B, is a ninth magnitude orange dwarf that takes 26.28 years to orbit at 10.3 AU around the primary in an elliptical orbit. The orbital distance ranges from 6.4 AU at periastron to 14.2 AU at apastron. 85 Pegasi B may itself be a binary, with a close, faint red dwarf companion (designated 85 Pegasi Bb) separated by 2 AU from the primary (designated 85 Pegasi Ba). The mass would be 11% solar mass (M☉). All components in the star system including Star A are smaller, cooler and less massive, luminous, and metallic than the Sun and 51 Pegasi.

HD 1317 - Totalement dominée

38 Piscium is a blue to white star located in the constellation of Pisces. It is not visible to the naked eye and requires a telescope to observe. Here are some key details about Star 38 Piscium:

Distance: Star 38 Piscium is approximately 49.53 light years away from Earth.

Age: The star is estimated to be around 10.2 billion years old, with a possible range of 8.3 to 11.9 billion years.

Spectral Type: It has a spectral type of F5, indicating it is a yellow to white star.

Location: Its celestial coordinates are Right Ascension 00h 17m 24.50 and Declination +08° 52` 34.8. This places it in the equatorial region of the celestial sky, making it visible from both hemispheres.

Iron Abundance: The star has an iron abundance of -0.27, which is lower than the Sun’s iron abundance.

Temperature: Based on its spectral type, the surface temperature of Star 38 Piscium is estimated to be between 6,000 and 7,500 Kelvin.
