Comet Nishimura, discovered by Japanese space photographer Hideo Nishimura, is set to make its closest approach to Earth this week, offering a celestial spectacle for stargazers. The comet, which completes one revolution every 430 to 440 years, will be visible with binoculars in dark skies away from city lights. Despite its greenish appearance in photographs, it will appear nearly colourless or slightly pink when viewed through binoculars.
