It’s only about half a mile wide but will pass the closest to Earth on Sept. 12 within 78 million miles of our home planet and will able to be over the next few days in the Northern Hemisphere. It will be brighter as it gets closer to Sept. 12, but will be lower on the horizon,You’ll want to be ready to go about one and a half hours before dawn next week, looking toward the constellation Leo, about 10 or fewer degrees above the horizon.
The comet is faint, but you can see it with the naked eye, however, you may want to grab something to help bring it more into focus, since “visible to the naked eye” means that it’s bright enough to be seen without aid but may resemble a smudge, the“So you really need a good pair of binoculars to pick it out and you also need to know where to look,” Paul Chodas told theYou can also use a telescope to see the Nishimura comet,It will show up one last time around Sept.
