Today I went to the museum of natural history. I wasn't really thrilled about it because I hate history. But it turned out to be fascinating.

   The Earth was formed many years ago by the big bang. It's hard to imagine planets crushing each other then forming it self again.

   The other planets were formed with big bang too. And eventually it created the solar system. There were 9 planets but it changed to 8 because pluto was too small for fitting in the solar system. 

   In the solar system, each presents a Greek god. Mercury represents Hermes (The god of theif), Venus represents Aprodite (The god of love), Mars represents Ares (The god of war), Jupiter represents Zeus (God of the sky), Saturn represents Kronos, Uranus represents Uranus(God of the heaven), Neptune represents Poseidon (The god of sea).

   When a planet turn on its axis it's called the "rotation" It only takes one day to do a rotation. When it revolves around the Sun it's called the "revolution" This takes 1 year. This cycle wouldn't end. It will keep pulling like a magnet or someone who likes you.
