Recent analysis of satellite data from GRACE reveals that processes deep within Earth's mantle, possibly involving mineral phase transitions, are causing changes in the planet's gravity field, with potential implications for understanding Earth's internal dynamics and magnetic field variations.
Earth's temporary mini moon, 2024 PT5, may be a fragment of the larger moon, according to a study suggesting its composition matches lunar samples from past missions. The bus-sized asteroid, which has been orbiting Earth since September, will leave on November 25. Despite debates over its classification as a 'mini moon,' researchers emphasize the significance of such objects in understanding space dynamics and potential commercial opportunities in space mining. The study is under review for publication in Astronomy & Astrophysics Letters.
