what i can't understand is...
The International Astronomical Union voted on an official definition of the word "planet" on Aug,24,2006.
celestial bodies must the following conditions in order to be classified as planets, the body must be in orbit around a star ,while not being itself a star, the body must be massive enough for its own gravity to pull it into a nearly spherical shape.
what i can't understand is 'the body must be massive enough for its own gravity to pull it into a nearly spherical shape.'
especially,, i dont know the meaning of ' pull into'..
give me easy explaination of 'pull into'
i guess... the meaning of 'pull into' isnt 'moving into some place and stoping there' , right?
so... what is the meaning of?
