In 1610, galileo discovered moons on this planet. what planet was discovered?

Hold up, hee-haw, whoa !  Back it up.

-- When Galileo decided to point his toy telescope at things
in the sky, he discovered moons circling the planet Jupiter.
Right now, in 2016, something like 65 moons of Jupiter are
known.  Galileo saw four of them.  You can see those too, if
you have binoculars and you know how to find Jupiter in the sky.  

-- The Moons aren't "on" Jupiter; they follow orbits around it,
at some considerable distance from it. 

-- Galileo didn't 'discover' Jupiter.  Jupiter is quite visible to
the unaided eye, and has been for several thousand years. 
That's a big part of the reason why Galileo decided to give it
a look-see with his telescope.

Acetic acid  /əˈsiːtɪk/, systematically named  ethanoic acid  /ˌɛθəˈnoʊɪk/, is a colourless liquid  organic compound  with the  chemical formula  ch3cooh (also written as ch3co2h or c2h4o2). when undiluted, it is sometimes called  glacial acetic acid.  vinegar  is no less than 4% acetic acid by volume, making acetic acid the main component of vinegar apart from water. acetic acid has a distinctive sour taste and pungent smell. in addition to household vinegar, it is mainly produced as a precursor to  polyvinyl acetate  and  cellulose acetate. it is classified as a  weak acid  since it only partially  dissociates  in solution, but concentrated acetic acid is corrosive and can attack the skin.acetic acidnamespreferred iupac nameacetic acidsystematic iupac nameethanoic acidother namesvinegar (when dilute); hydrogen acetate; methanecarboxylic acid[1][2]identifierscas number64-19-7  3d model (jsmol)interactive image3dmetb00009 reference506007chebichebi: 15366  chemblchembl539  chemspider171  drugbankdb03166  echa infocard100.000.528ec number200-580-7e numbere260  (preservatives)gmelin reference1380iuphar/bps1058keggd00010  meshacetic+acidpubchem  cid176rtecs numberaf1225000uniiq40q9n063p  un number2789inchiinchi=1s/c2h4o2/c1-2(3)4/h1h3,(h,3,4)  key:   qtbsbxvteameqo-uhfffaoysa-n  smilescc(o)=o
