How many estimated planets are there in the universe?
There may be two-to-three trillion planets in our whole universe.
The above figure is just a rough estimation. There can be many more planets as we still are not able to venture through the whole universe.. What we are guessing is just 5% of the total number of planets.
Take our Milky Way, It has several solar systems which has approximately 10 - 100 planets revolving around them...
But there are 100 billion Earth- Like planets out in the observable universe.
