Trillions of Worlds WIthout Stars | Exoplanet Radio ep 25
Astronomers estimate that there are more free roaming planets in our galaxy than there are planets in orbit around stars.
In fact, rogue exoplanets - planets with no star whatsoever - far outnumber all other planets in our galaxy, by 20 times. Trillions of worlds wandering alone.
Astronomers have reached this conclusion based on the results of a nine year survey that looked at special events that occur when an object such as a star or planet comes into near-perfect alignment with an unrelated background star from our vantage point.
