1

HD 195 019 is about 37 parsecs distant star system in the constellation dolphin. It consists of two stars at an angular distance of 4 ", 1 (150 AU) with a position angle of 324 °. Moreover, the main component is surrounded by a spectroscopic companion, in which there is a potential exoplanets. The central star has a apparent magnitude of 6.9 on like and belongs to the spectral type G3 IV-V, its mass is approximately that of the sun.

Potential exoplanet

HD 195 019 B is a potential Exoplanet which surrounds the main component with a period of 18 days, with its path of about 0.01 has a low eccentricity. Its minimum mass is ( 3.7 ± 0.3 ) Jupiter masses. It could be a "hot Jupiter", with an estimated average surface temperature of 755 Kelvin. The property was in 1998 by Geoffrey Marcy et al. discovered with the radial velocity measurement method.
