Sonmassa
Sonmassa (M☉) is ’n standaard-massaeenheid in sterrekunde wat gebruik word om die massa van ander sterre, sterreswerms, newelvlekke en sterrestelsels aan te dui.
Dit is gelyk aan die massa van die son, sowat twee noniljoen kilogram.
’n Noniljoen kilogram:
- 1 M☉= 1,98892±0,00025×1030 kg
Dit is sowat 332 950 keer die massa van die Aarde (332 950 M⊕) of 1 048 keer die massa van Jupiter (1 048 MJ).
