Brahaspati (pratiik: , Jupiter), Saur mandal (Solar System) ke sab se barraa grah (planet) hae.
aur ii Suraj se duur 5th planet hae. Brahaspati ke ek gas giant planet bola jaawe hae, kaahe ki ii bahut barraa hae aur gas se banaa hae. Duusra giant planet hae Sanigrah (Saturn), Arungrah (Uranus) aur Varungrah (Neptune). Brahaspati ke wajan 1.8986×1027 kg hae jon ki Dunia se 317.8 dafe jaada hae. This is twice the mass of all the other planets in the Solar System put together.

Brahaspati ke purana Romans log jaanat rahin aur uu logan iske Roman god, Jupiter, (Latin: luppiter) ke naam ke baad rakkhin rahaa. Brahaspati, raat ke aasmaan me tiisra sab se brightest object hae, Chandarma aur Venus ke baad me. Brahaspati ke lage kamti se kamti 63 chandarma hae, jisme se 55 5km diameter se chhota hae. Chaar khaar chandarma hae Io, Europa, Ganymede aur Callisto.
Brahaspati, Solar System ke sab se barraa planet hae, jiske diameter 142,984 km hae. Ii dunia ke diameter se 11 dafe jaada hae.
Brahaspati ke surface ke hawaa me 85.8 to 89.8% hydrogen, 8.2 to 12.2% helium, aur 1% duusra gas hae. Planet ke aur bhittar jaao tab bahut garam rahe hae aur pressure etna jada rahe hae ki helium ras ban jaae hae aur planet ke bhitar paani barrse hae. Brahaspati ke gas Saturn ke rakam hae lekin ii Neptune aur Uranus se different har jahaan pe aur kamti hydrogen aur helium gas hae.
Jaada garmi aur pressure ke kaaran scientist logan ii nai batae sake hae ki Brahaspati ke biich me kon chij hae, kaahe ki ii rakam ke pressure dunia me nai mile hae. Iske biich se thorra bahar jaao tab ek mota hydrogen ke ras hae. Ii pressure etna jaada hae ki hydrogen karraa hoe jaawe hae lekin fir se garmii ke kaaran ras ban jaawe hae.
Brahaspati solar system ke aur sab planet ke jorr ke dugna garrhuu hae. Because of all the gas near the core, it gives off more heat than it gets from the sun. Brahaspati, Dunia se 11 dafe jaada lamba hae aur 318 dafe jaada garrhu hae. Iske volume, Dunia ke volume se 1,317 dafe jaada hae, iske matlab ii hae ki 1,317 dunia isme fit hoe jaawe sake hae.
