Among all the wonderful scientific achievements in 2022, astronomers have found more than 300 exoplanets – planets that are outside our solar system.
NASA confirmed in March that there are now more than 5,000 known exoplanets, but this is only a small fraction of those that exist in the Milky Way alone.
As of Thursday, this number now stands at 5,235 – up 351 from exactly a year ago – although experts have discovered new facts about already-known exoplanets too.
