Ny kintanantsika: loharanon’ny angovo rehetra eto amin’ny tany, ary ny fipetrahana izay mitazona ny planeta tsirairay ao anatin’ny lalany.

The Sun is a G-type main-sequence star (spectral type G2 V) about 4.6 billion years old. It shines by fusing hydrogen into helium in its core, where the temperature is about 15.7 million kelvin. Its visible surface, the photosphere, has an effective temperature of 5,772 K.
Tsy miova toy ny zavatra mavesatra izy: ny equator-ny dia miova isaky ny 25 andro eo ho eo ary ny tafikany isaky ny 35 andro eo ho eo. Ny planeta, ny kintana ary ny zavatra hafa rehetra ao amin’ny rafi-masoandro dia mivezivezy manodidina azy.
