Assuming a Jupiter-like composition, its # 3 with Newton 's Universal Gravitation, we can calculate the mass: by combining Kepler # 3 Newton. It has a mass 46 percent that of Jupiter and orbits surprisingly close (7.8 million km [4.8 million miles]) to the star—much closer than Mercury orbits the Sun (at a distance of 57.9 million km [35.9 million miles]). After its discovery, many teams confirmed its existence and obtained more observations of its properties, including the fact that it orbits very close to the star, experiences estimated temperatures around 1200 °C, and has a minimum mass about half that of Jupiter. (news Calculate the mass: By combining Kepler #3 with Newton's Universal Gravitation, we can calculate the mass of 51 Pegasi b. from the Stars, The new method reveals 51 Pegasi b has a mass about half that of Jupiter's and an orbit with an inclination of about nine degrees to the direction to the … Its orbit may be inclined by less than 85° from the perspective of an observer on Earth Henry et al, 1997).

Spoilers The Occupant, The sinusoid is the characteristic shape of the radial velocity graph of a star rocking to the tug of an orbiting planet. Instead of an absolute mass in kilograms, we will calculate based on comparison to Jupiter. 51 Pegasi b (51 Peg b) was the first discovered planetary-mass companion of a main-sequence parent star. 51 Pegasi b was found to have a mass about half that of Jupiter's and an orbit with an inclination of about 9 degrees to the direction to the Earth. For an illustration, see David Haworth's It was detected by radial-velocity observations obtained with the Elodie spectrometer on the 1.93-m telescope at the Observatoire de Haute Provence in France (Mayor and Queloz 1995). from the star), as simulated by Stimac Beneath this, the gases that make up the planet would be so hot that the planet would glow red.
