A probabilistic age prior analysis give a current mass of 16.5–19 M ☉ and an initial mass of 18–21 M ☉. [11] Betelgeuse's mass can also be estimated based on its position on the color‑magnitude‑diagram (CMD). Betelgeuse's color may have changed from yellow (or possibly orange; i.e. a yellow supergiant) to red in the last few ...
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. These lists can be sorted according to an object's radius and mass and, for the most ...
−119 [d] or ~R Betelgeuse: L/T eff & AD Widely recognised as being among the largest known stars. [21] Might be the largest star visible to the naked eye. [30] The higher radii estimate assume Mu Cephei is in the Cepheus OB2 OB association. [28] [31] Other sources suggest Mu Cephei and Betelgeuse are likely similar in properties.

Stars fuse (meld together) various elements, depending on their age and mass. By studying movements (like sound waves) on the surface of the star suggest Betelgeuse is still fusing helium.
The gram (10 −3 kg) is an SI derived unit of mass. However, the names of all SI mass units are based on gram, rather than on kilogram; thus 10 3 kg is a megagram (10 6 g), not a *kilokilogram. The tonne (t) is an SI-compatible unit of mass equal to a megagram (Mg), or 10 3 kg.

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 .
