Earth to capture temporary mini-moon asteroid this weekend
Earth will temporarily capture a small asteroid, named 2024 PT5, this Sunday, September 29. This "mini-moon" will orbit Earth for a few weeks before returning to its usual path around the sun. Unlike the permanent moon, which has been with Earth for about 4 billion years, 2024 PT5 is only about 37 feet wide. It will not be visible to most amateur astronomers due to its small size and dimness. This event is part of a common phenomenon where Earth captures asteroids briefly. Previous captures have lasted from a week to several years, but 2024 PT5 will only be around until November 25.
