Northern circumpolar constellations, image: Roberto Mura. What effect or effects would be most significant if the Moon's orbital plane were exactly the same as the ecliptic plane? Depending on the amount of light pollution around you, it may be hard to make out the entirety of this constellation; however, Polaris will still most likely be visible in any condition. Viewed from Earth's equator, the celestial equator begins at the eastern horizon, passes directly overhead and drops down to the western horizon.

It is one of the most conspicuous [1] and recognizable constellations in the night sky. The term circumpolar refers to constellations and stars that are circling the north and south celestial poles without ever dipping below the horizon. E) there are never two solar eclipses in the same year. B) speeding up Earth's orbital motion Another famous nebula is IC 434, the Horsehead Nebula, near Orionis. [49], The imagery of the belt and sword has found its way into popular western culture, for example in the form of the shoulder insignia of the 27th Infantry Division of the United States Army during both World Wars, probably owing to a pun on the name of the division's first commander, Major General John F.

It consists of the three bright stars Zeta (Alnitak), Epsilon (Alnilam), and Delta (Mintaka). The constellation contains a total of 281 stars brighter than magnitude 6.5, visible to the unaided eye in good observing conditions. B) Solar eclipses would be much more frequent. These conditions, along with the tilt and position of the Earth in its orbit, make observing the summer sky a little more difficult.
