It is a nearly perfect sphere of hot plasma, with internal convective motion that generates a magnetic field via a dynamo process. Surface temperature: 5,778 K

Radius: 695,700 km

Mass: 1.989 × 10^30 kg

Escape velocity (from the surface): 617.7 km/s; 55 × Earth

Equatorial surface gravity: 274.0 m/s2; 27.94 g; 27,542.29 cgs; 28 × Earth

Did you know: The Sun is the brightest star by apparent visual magnitude (V = −26.74)
