Solar System other bodies orbiting the Sun. The principal component of the Solar System is the Sun, a G2 main-sequence star that contains 99.86% of the system's known mass and dominates it gravitationally. The Sun's four largest orbiting bodies, the giant planets, account for 99% of the remaining mass, with Jupiter and Saturn together comprising more than 90%. The remaining objects of the Solar System (including the four terrestrial planets, the dwarf planets, moons, asteroids, and comets) together comprise less than 0.002% of the Solar System's total mass. Most large objects in orbit around the Sun lie near the plane of Earth's
HD 170469 b make orbital velocity of 19.8 km/s, slower than Earth's 29.8 km/s. HD 170469 b HD 170469 b is a gas giant exoplanet located approximately 212 light-years away in the constellation Ophiuchus, orbiting the star HD 170469. This planet was discovered in April 2007. The star is 1.1 solar mass and the planet is at least 67% the mass of Jupiter, orbiting about half the distance of Jupiter from the Sun. The mass value is only minimum since the inclination is unknown. The orbital distance is more than twice the distance from Earth to the Sun, although taking over three Earth
