How many Planets alike Earth are there in Solar System

Some Questions

Pennsylvania: By counting a single Hair it can be said how many hairs do you have in your head but it is impossible to tell how many galaxies are in this universe? How many stars are there in each galaxy? How many of these stars are like our sun? And how many planets orbiting our Earth are there around each star like our sun? Everything we know about it is nothing but the best and most careful way.

Despite all this, a team of astronomers at Pennsylvania State University has estimated the computer simulations, based on the properties of the planets discovered so far and the origins of their central stars, in each of the four like our sun. On average there is at least one planet orbiting our planet around a star. However, this "probable number" can be as large as 33 sunlight from a planet like Earth.

Earth-like planet

But here it is necessary to define "our planet like Earth".
When called "Earth-like planet" in astronomy, it refers to any planet whose size ranges from three quarters (75 percent) to one-half times (150 percent) lower than our Earth; From the 237 earthy days to the 500 star days around the central star (sun), I complete a cycle.

So far, 4,031 planets orbiting other stars have been discovered, of which approximately 40 correspond to our Earth. These estimates will serve as space explorations that will be sent over the next few years to explore Earth-like planets in our universe.

In Trillions

Talking on estimates alone, the latest estimates suggest that the total number of galaxies in the universe could be around 2000 billion (2 trillion). Almost 100 billion stars like our sun are possible in every galaxy. That is, the minimum number of Earth-like planets in the universe can be more than 6000 billion (6 trillion).

Now how many of these planets will there be where Earth-like life has come into being? And then that life would have evolved into an intelligent and inventive creature like us? We have no answer to these questions; and we do not know whether we will get a definitive answer or not.
