HD 192699 b
HD 192 699 b is an exoplanet, the yellow sub- giant orbiting HD 192 699. Due to its high mass is assumed that it is a gas planet.
Discovery
As the majority of exoplanets was also discovered that using the radial velocity method. The data comes from observations of the Keck and Lick observatories. The discovery was published by John Asher Johnson and staff in August 2007. At the same time the discovery of exoplanets HD 175 541 b and HD 210702 b was announced.
Web properties
The planet orbits its star at an average distance of approximately 1.16 astronomical units. With its relatively high eccentricity of 14.9 % of the distance varies within a planet's year from 1.15 to 1.33 astronomical units. A revolution takes 351.5 Earth days. This is in spite of the slightly wider compared to Earth orbit less than one Earth year, as HD 192 699 b due to the high mass of its central star a higher path velocity ( 36.0 km / s to 29.8 km / s) has.
Physical Properties
HD 192 699 b has a minimum mass of about 794.8 Earth masses and 2.5 Jupiter masses. The true mass can not be determined without knowledge of the orbital inclination to the observer location, so for the time being remains unclear. In all likelihood, HD 192 699 b has a Jupiter-like expansion and is correspondingly thicker.
