Comet C/2022 E3 (ZTF), which is set to make a close approach to the Earth on Wednesday, may have originated in a mysterious cloud at the edge of the solar system.

The comet, which may be faintly visible to the naked eye at night from dark sky locations, if you know where to look, is currently more than 27 million miles from Earth.
