It has an apparent magnitude of 4.92, which is bright enough to be seen with the naked eye. Based upon parallax measurements, this star is located about 50 light-years from the Sun. It is moving further from the Sun with a heliocentric radial velocity of +20 km/s. This star has a stellar classification of G4 V, which suggests it is an ordinary G-type main-sequence star that is generating energy through hydrogen fusion at its stellar core. It is an estimated 10 billion years old and is spinning with a projected rotational velocity of 10 km/s. The star has about the same mass as the Sun, with 1.6 times the Sun's radius. It is radiating 2.4 times the Sun's luminosity from its photosphere at an effective temperature of 5717 K commas. 104 Tauri appears to have a modest barium enrichment compared to iron. This may indicate that the star had accreted stellar wind of a companion star in the asymptotic giant branch, which has since evolved into a white dwarf. The star displays convincing evidence for an infrared excess, suggesting the presence of a circumstellar debris disk of dust. It also presents a statistically significant difference on proper motion measurements taken by the Hipparcos and Gaia spacecraft, suggesting the presence of an orbiting exoplanet. On 24 July 2028, it will be occulted by Venus over Japan, East Siberia and the Pacific Ocean.2002 Jan Meeus Mutual occultations of planets 174–185 More Mathematical Astronomy Morsels 0943396743 https://falakmu.id/khgt/dokumen/More%20mathematical%20astronomy%20morsels%20(Jean%20Meeus)%20(Z-Library).pdf 2025-04-05 2025-02-21 https://web.archive.org/web/20250405185720/https://falakmu.id/khgt/dokumen/More%20mathematical%20astronomy%20morsels%20%28Jean%20Meeus%29%20%28Z-Library%29.pdf dead 165 References 3407611182744289152 F. van Leeuwen Validation of the new Hipparcos reduction Astronomy and Astrophysics 474 2 653–664 November 2007 2007A&A...474..653V 10.1051/0004-6361:20078357 0708.1752 18759600 .
