Witness the cosmic spectacle of Comet Nishimura! •

This half-mile-sized green comet is gracing our skies for a fleeting moment, visible from the Northern Hemisphere for just five magical mornings.

Mark your calendars for Sept. 12th when this icy wanderer will be closest to Earth, though still at a safe distance of 78 million miles. Set your alarms for 90 minutes before dawn and gaze toward the northeastern horizon for a stunning view! «.

Comet Nishimura glides gracefully, just 10 degrees above the horizon, near the constellation Leo.
