The last mini-moon to visit Earth was 2020 CD3, which circled Earth for a few months before it flew off to orbit the sun in March. Now, Deborah Byrd and Eddie Irizarry write for EarthySky.org that scientists have identified another piece of space stuff that is expected to join Earth’s orbit, known as 2020 SO.
