There are something like 2 trillion galaxies.....

  

There are something like 2 trillion galaxies or in other words, two trillion 2000 billion galaxies and each Galaxy is around the size of Milky Way.

The Milky Way has 400 billion stars in it and would take over 100,000 years to cross. Most stars have planets. In our Galaxy there are anywhere between 800 billion to 3 trillion planets. Of that number, at least 300 million are potentially habitable.

Scientists are sure that the piece of the universe we can see is only fraction, a small fraction, of what’s out there but assume, based on research, that there are between 100 billion to 2 trillion galaxies in the universe, or, in other words, a billion trillion stars.
