Oct 24, 2024 · HD 195019 b is a gas giant exoplanet that orbits a G-type star. Its mass is 3.98 Jupiters, it takes 18.2 days to complete one orbit of its star, and is 0.14 AU from its star. Its discovery was announced in 1998.

HD 195019 b is an exoplanet orbiting around HD 195019 in the binary star system. It has a minimum mass of 3.7 M J. It orbits very close to the star. Like many planets at close distance, its orbit is circular, even more circular or less eccentric than Earth. It takes 437 hours to orbit with velocity of 83.24 kilometers per second. [1]

Binary star HD 195019 is located 123 light years away from the Sun. It consists of a subgiant and a orange star. There is at least one exoplanet in this system.

HD 195019 is a seventh magnitude (6.91) star in Delphinus that is below naked eye vision (though easily accessible with binoculars) and classed as a G3 subgiant-dwarf (implying that it is close to giving up core hydrogen fusion).

Jan 1, 1999 · In July and August, we observed 82 of these stars, and here we present two planet candidates around the chromospherically quiet G dwarfs, HD 195019 and HD 217107. The planet around HD 195019 has an orbital period of 18.27 days, similar to that of 55 Cnc ( P = 14.7 days).

HD 195019 is a subgiant star located in the constellation of Delphinus, The Dolphin. It is not part of the Delphinus constellation outline but is within the borders of the constellation. Based on the spectral type (G3IV-V), HD 195019 colour is yellow, a mid-ranged temperature star.

Oct 26, 1998 · The G3V/IV star, HD 195019, exhibits Keplerian velocity variations with a period of 18.27 d, an orbital eccentricity of 0.03 +/- 0.03, and M sin i = 3.51 M_Jup. Based on a measurement of Ca II H&K emission, this star is chromospherically inactive.
