200 billion stars (potential solar systems) in our galaxy
According to current estimates, our galaxy, the Milky Way, likely contains hundreds of billions of solar systems, as there are estimated to be around 200 billion stars in our galaxy, and most stars are expected to have planets orbiting them, creating multiple solar systems.
The number of galaxies in the universe is estimated to be between hundreds of billions and two trillion, but the exact number is unknown. Estimates have varied over time as telescope technology has improved:
100–200 billion This estimate is based on multiplying the number of galaxies in a small patch of sky by the number of times that patch would fit into the entire sky.
2 trillion - This estimate is based on computer simulations that try to match what telescopes see with the number of galaxies that might be too small, faint, distant, or hidden by gas and dust. However, a 2021 study using data from NASA's New Horizons spacecraft suggests that the number of galaxies is more likely in the hundreds of billions.
Infinite - Some research suggests that the universe may be infinite, which would imply that there could be an infinite number of galaxies.
