The Earth has a newly discovered neighbor in the form of a "quasi-moon" that appears to be following us around through space.

The newly discovered object, named 2023 FW13, is an asteroid measuring around 50 feet in diameter that orbits the sun at around the same rate as the Earth, and circles around our planet in a sweeping oval-shaped object as it does so.
