The Sun as it is seen from Earth.

Suraj (pratiik: ) ek tara hae aur saur mandal (solar system) me sab se baraa chij hae. Isme solar system ke 99.86% wajan hae. Sab se barraa grah, Jupiter, Suaraj ke saamne bahut chhota hae. Solar system ke grah Suraj ke round chakkar maare hae. Ham log ke Suraj din bhar aasmaan me dekhae hae. Ii ek barraa piyar ball ke rakam dekhe me lage hae. Suraj asliyat me ek barraa taara hae jisme plasma sab time bubble hoe hae. Ii explosion se etna energy nikle hae ki Suraj ke 1 second ke power United States ke 9 million saal talak power kare sake hae. Jab ki Suraj, dunia se 93 million miles (150 million km) duur hae, iske taagat ke ham log feel karta hae.
