SPACE-JUPITER

JUPITER  IS   FIFTH  PLANET   FROM  THE  SUN,  and   first  of  the  four  gas  giants.It  is    the  largest   and  most  massive  planet ,  with  a  diameter    about  11  times   that  of  the  Earth   and  a  mass  about    2.5  times   the  combined  mass  of  eight  other  planets .Jupiter  is  thought  to  have   a  small  rocky  core   surrounded  by  an  inner   mantle   of  metallic   hydrogen  (liquid  hydrogen   that  acts  like  a  metal.,  outside  the  inner  mantle   is  an  outer  mantle   of  liquid   hydrogen  and   helium  that  merges  into  the  gaseous  atmosphere .
Jupiter's   rapid    rate  of  rotation   causes  the  clouds  in  its  atmosphere  to  form  belts   and  zones   that encircle    the  planet   parallel   to the  equator .Belts  are  dark  , low lying  ,relatively  warm  cloud layers .Within  the    belts  and  zones ,turbulence   causes   the formation  of cloud  features    such    as  white  ovals   and  red  spots ,  both  of  which  are   huge   storm  systems.
The  most  prominent   cloud  features   is  a   storm  called    the great   red  spot ,    which  consists  of   a  spiralling  column   of  clouds   three  times  wider  than the  Earth    that  rises   eight  kilometres   above  the  upper  cloud  layer .Jupiter  has   one  thin  faint,  main  ring ,  inside  which is a  tenuous  halo  ring   of  tiny   particles  extending  towards   the  planet .There  are  16  known  jovian  moons .The  four  largest  moon  are   Ganymede,Callisto,Io,and  Europa.Ganymede  and  Callisto   are  cratered,  and  probably  icy.Europa  is   smooth  and  icy. and  may  contain  water.Io  is  covered   in  bright  red ,  orange,and yellow  splotches .This  co louring  is  caused   by   sulfurous   material  from  active  volcanoes   that  shoot  plumes   of lava   hundreds  of  kilometers   above  the  surface.
