Comet C/2020 M3 ATLAS is passing through our vicinity, and makes its closest approach to Earth this Saturday, 14 November.
Of course it’s not new at all, but new to us; it was discovered earlier this summer by the University of Hawaii-NASA Project ATLAS. C/2020 M3 will pass somewhat more than 50 million kilometers from Earth, and is close enough and bright enough to be seen against the constellation Orion with a good pair of binoculars as it passes through.
