The Sun is a G2-type main-sequence star. Hotter main-sequence stars are more luminous.
The Sun's temperature is intermediate between that of the hottest stars and that of the coolest stars.
Stars brighter and hotter than the Sun are rare, whereas substantially dimmer and cooler stars, known as red dwarfs, make up 85% of the stars in the Milky Way. source

The English proper name Sun developed from Old English sunne and may be related to south.
The English weekday name Sunday stems from Old English (Sunnandæg; "Sun's day", from before 700) and is ultimately a result of a Germanic interpretation of Latin dies solis.
The Sun is by far the brightest object in the sky, with an apparent magnitude of −26.74.
The mean distance of the Sun's center to Earth's center is approximately 1 astronomical unit (about 150,000,000 km; 93,000,000 mi)
The Sun's color is white, with a CIE color-space index near (0.3, 0.3), when viewed from space or when the Sun is high in the sky source
