700 quintillion planets There are over 700 quintillion planets in the universe — but there's no place like home.

As of now, there are over 4,000 confirmed extrasolar planets, also known as exoplanets, in our universe. This number is constantly growing as new planets are discovered through various astronomical techniques.
It is difficult to determine the exact number, but based on current estimates and the vastness of the universe, scientists believe there could be billions of Earth-like planets in the observable universe.
There are more than 10 billion trillion Earth-like planets (100 billion+ per galaxy/1 or 2 per star) in the universe, and estimates may vary.
There is no definitive answer to how many infinite planets there are in the universe. The universe is vast and constantly expanding, with potentially countless planets beyond what we can currently observe.

We can never know how many planets there are in the entire universe.

Currently there are 353 known extrasolar planets (that is to say, outside of our solar system), but it is unknown how many planets exist in the universe.
It is currently unknown how many Earth-like planets exist in the universe. Scientists have discovered thousands of exoplanets, some of which may have conditions favorable for life, but the exact number of Earth-like planets is still uncertain due to the vastness of the universe.

There are at least 10 billion trillion Earth-like planets (with 100 billion per galaxy) in a fictionalized version of our universe.
We have no way of knowing how many, although we do now know that there are other star systems with planets, or notable "accretion discs" (from which planets will form). It is a very difficult area to explore because planets, even very big planets, are a fraction of the size of the stars they surround, and the stars themselves are difficult enough to see. As far as "how many in the universe?" undoubtedly a large amount, but we have absolutely no idea how many that might be.
Hydrogen makes up about 75% of the universe by mass. It is the most abundant element in the universe and can be found in stars, gas clouds, and planets.
No-one can possibly know for sure, but the answer is probably billions. There are hundreds of billions of stars in our own Milky Way galaxy, many of which have solar systems of their own, and as many galaxies in the Universe as there are stars in our own galaxy (and the Milky Way is by no means a particularly large galaxy, just of average size). If you take all of this into account, the number of planets likely to be in the universe would be many billion.
There are 10 million trillion Earth-like planets with sentient life (100 million per galaxy) in a fictionalized version of our universe.
