    en.wikipedia.org/wiki/Astronomical_system_of_units

    The solar mass (M ☉), 1.988 92 × 10 30 kg, is a standard way to express mass in astronomy, used to describe the masses of other stars and galaxies. It is equal to the mass of the Sun , about 333 000 times the mass of the Earth or 1 048 times the mass of Jupiter .

  3. 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 .

    Average distance of Earth's orbit from the Sun (sunlight travels for 8 minutes and 19 seconds before reaching Earth) — Mars: 1.52 — Average distance from the Sun — Jupiter: 5.2 — Average distance from the Sun — Light-hour: 7.2 — Distance light travels in one hour — Saturn: 9.5 — Average distance from the Sun — Uranus: 19.2 ...

  5. 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 ...

  6. Jupiter - Wikipedia

    But the Solar System never developed into a system of multiple stars and Jupiter does not qualify as a protostar or brown dwarf since it does not have enough mass to fuse hydrogen. [ 28 ] [ 29 ] According to the " grand tack hypothesis ", Jupiter began to form at a distance of roughly 3.5 AU (520 million km ; 330 million mi ) from the Sun.

  7. Solar radius - Wikipedia

    en.wikipedia.org/wiki/Solar_radius

    695,700 kilometres (432,300 miles) is approximately 10 times the average radius of Jupiter, 109 times the radius of the Earth, and 1/215th of an astronomical unit, the approximate distance between Earth and the Sun. The solar radius to either pole and that to the equator differ slightly due to the Sun's rotation, which induces an oblateness in ...

    Jupiter's ancient name really is well-deserved: according to a new study, the king of the planets isn't just the largest in the Solar System, it's also the oldest.

  9. Jupiter mass - Wikipedia

    en.wikipedia.org/wiki/Jupiter_mass

    The Jupiter mass, also called Jovian mass, is the unit of mass equal to the total mass of the planet Jupiter. This value may refer to the mass of the planet alone, or the mass of the entire Jovian system to include the moons of Jupiter. Jupiter is by far the most massive planet in the Solar System. It is approximately 2.5 times as massive as ...
