How Many Planets And Galaxies Are In The Universe. He found that — given our current understanding of the universe and the laws of physics — there should be 7 times 10 20 planets in the universe. Add in the eight in our solar system (not nine, sorry pluto), and that gives us a total of 5,510 known planets, all located in our own. A crude estimate would be to take the number of planets thought to be in the milky way and times it by 54, so this would be 54 times 400. Astronomers think the youngest known galaxy. Astronomers estimate that there is roughly one exoplanet per star in our galaxy. And some stars have none. That’s 7 followed by 20 zeroes or 70. Most galaxies are between 10 billion and 13.6 billion years old. Currently, in 2020, it was estimated that there are around 2 trillion galaxies in the observable universe. Some are almost as old as the universe itself, which formed around 13.8 billion years ago. With an estimated ~2 trillion galaxies in our observable universe, we can finally make an accurate estimate of the total number of planets.
