Unità atomiche. ≈ 2,1955 × 1060 m e. Modifica dati su Wikidata · Manuale. In astronomia, la massa solare (simbolo M☉) è un'unità di misura, usata per esprimere la massa delle stelle e di oggetti più grandi quali le galassie. Equivale alla massa del Sole, pari a circa due quintilioni di chilogrammi.
The Sun is the Solar System's star and by far its most massive component. Its large mass (332,900 Earth masses), which comprises 99.86% of all the mass in the Solar System, produces temperatures and densities in its core high enough to sustain nuclear fusion of hydrogen into helium.

The astronomical unit of mass is the solar mass. [1] . The symbol M☉ is often used to refer to this unit. The solar mass ( M☉ ), 1.988 92 × 1030 kg, is a standard way to express mass in astronomy, used to describe the masses of other stars and galaxies.
List of Solar System objects by size. Parts-per-million chart of the relative mass distribution of the Solar System, each cubelet denoting 2 × 10 24 kg. This article includes a list of the most massive known objects of the Solar System and partial lists of smaller objects by observed mean radius.
The Earth mass is a standard unit of mass in astronomy that is used to indicate the masses of other planets, including rocky terrestrial planets and exoplanets. One Solar mass is close to 333 000 Earth masses. The Earth mass excludes the mass of the Moon.
Solar mass is a unit of measurement of mass. It is equal to the mass of the Sun, about 332,950 times the mass of the Earth, or 1,048 times the mass of Jupiter. Masses of other stars and groups of stars are listed in terms of solar masses. Its mathematical symbol and value are: (kg being kilograms) Categories: Astronomy.
