NGC3918 Daily Motion
NGC3918 is said to be "never-rising." It is always below the horizon and remain out of view, regardless of the time of year or night.NGC3918 will be visible until January, 1, when it will move too close to the Sun. During this time, its proximity to the Sun will cause it to disappear from the night sky, making it unobservable for a while.
