Our Milky Way galaxy is an immensely interesting place. It has already been estimated that the Milky Way could be home to billions of alien planets.
So far, astronomers have been able to find around 1,000 planets in the Milky Way, with just a few of these thought to be potentially habitable.
But a new study by planetary scientists suggests that there could be more than 200 billion Earth-like planets in our galaxy alone.
The scientists from the Australian National University (ANU) made this claim based on applying a 200-year-old method known as Titius-Bode relation. This method estimates that the standard star has an average of two Earth-like planets in the habitable zone of each star.
Since the Milky Way has about 100 billion stars, this would mean hundreds of billions of potentially habitable planets in the galaxy.
