So far 4,031 extra-solar planets have been discovered, of which nearly 40 correspond to our Earth.

Perhaps by counting a single ball it can be said how many hairs you have in your head, but it is almost 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 are rotating around our Earth like every star in 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 discovered the planet’s locations so far and with the help of computer simulations made based on the properties of their central stars that we are rotating at least one planet around our Earth like an average of every 4 stars, like our sun. However, this potential number can be as close to the Earth as one of two sun-like planets to another planet, but to one of the 33 sun-like planets.But here it is necessary to explain our planet like the earth.
In astronomy, when called a planet like Earth, it means any such planet which amounts to three-fourths (75%) to one-half (150%) less than our land, and who completes a cycle around his main star (sun) from 237 earthy days to 500 earthy days. So far 4,031 planets have been discovered orbiting around other stars, about 40 of which match our land. These estimates will serve as space explorations that will be sent over the next few years to explore Earth-like planets in our universe.
The latest estimates indicate if you are talking about estimates only 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 entire universe may be slightly more than 6000 billion 6 trillion. Now how many of these planets will there be where Earth-like life has come into existence? And then that life would have evolved into the kind of 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.
Note: Details of this research are published in the latest issue of The Astronomical Journal.
