The Sun is 864,400 miles (1,391,000 kilometers) across. This is about 109 times the diameter of Earth. The Sun weighs about 333,000 times as much as Earth. It is so large that about 1,300,000 planet Earths can fit inside of it.

147.83 million km  – 147,830,000 km

often rounded to 150,000,000 km for rough calculations

The Sun is a G2V type star, a yellow dwarf and a main sequence star

with G2 indicating its surface temperature of approximately 5,778 K (5,505 °C, 9,941 °F), and V that it, like most stars, is a main–sequence star.
