How many solar systems are in the Andromeda galaxy?

The Andromeda Galaxy, which is the closest spiral galaxy to the Milky Way, is estimated to contain around one trillion stars. Given that many of these stars are likely to have planetary systems, it's reasonable to suggest that Andromeda could host hundreds of billions of solar systems. However, the exact number remains uncertain as current observational capabilities limit our ability to detect and study these systems in detail.
