    For example, if a TNO is incorrectly assumed to have a mass of 3.59 × 10 20 kg based on a radius of 350 km with a density of 2 g/cm 3 but is later discovered to have a radius of only 175 km with a density of 0.5 g/cm 3, its true mass would be only 1.12 × 10 19 kg.

    On 29 July a Falcon Heavy rocket launched the Jupiter-3 (EchoStar-24) [34] communications satellite to geosynchronous orbit. With a mass of over 9 tonnes, EchoStar's Jupiter-3 is the heaviest geostationary satellite ever launched. [35] On 1 June, Caltech reported the first successful demonstration of solar energy from space via its SSPD-1 ...

  4. Solar mass - Wikipedia

    en.wikipedia.org/wiki/Solar_mass

    The solar mass (M ☉) is a standard unit of mass in astronomy, equal to approximately 2 × 10 30 kg (2 nonillion kilograms in US short scale). It is approximately equal to the mass of the Sun. It is often used to indicate the masses of other stars, as well as stellar clusters, nebulae, galaxies and black holes. More precisely, the mass of the ...

    en.wikipedia.org/wiki/Solar_System

    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 ...

  6. Planetary mass - Wikipedia

    en.wikipedia.org/wiki/Planetary_mass

    The choice of solar mass, M ☉, as the basic unit for planetary mass comes directly from the calculations used to determine planetary mass.In the most precise case, that of the Earth itself, the mass is known in terms of solar masses to twelve significant figures: the same mass, in terms of kilograms or other Earth-based units, is only known to five significant figures, which is less than a ...

  7. Jupiter - Wikipedia

    en.wikipedia.org/wiki/Jupiter

    It is a gas giant with a mass more than 2.5 times that of all the other planets in the Solar System combined and slightly less than one-thousandth the mass of the Sun. Its diameter is eleven times that of Earth, and a tenth that of the Sun. Jupiter orbits the Sun at a distance of 5.20 AU (778.5 Gm), with an orbital period of 11.86 years.

  8. Jupiter mass - Wikipedia

    en.wikipedia.org/wiki/Jupiter_mass

    Jupiter's mass is 2.5 times that of all the other planets in the Solar System combined—this is so massive that its barycenter with the Sun lies beyond the Sun's surface at 1.068 solar radii from the Sun's center. [4] Because the mass of Jupiter is so large compared to the other objects in the Solar System, the effects of its gravity must be ...
