How many galaxies are there in the Universe? Currently, the observable Universe, which has a radius of 46.5 billion light-years, seems to contain at least two trillion galaxies.
Our galaxy, the Milky Way, is just one among these numerous galaxies, and it isn’t even considered a big galaxy. It stretches for 105,700 light-years in diameter and may contain at least 100 billion planets and around 400 billion stars.
