Orion Nebula (M42) Observation Details
M42 Daily Motion
M42 will rise at 22:34, during twilight, and will ascend to 47° by the time twilight ends at 04:03.M42 will be visible until April, 10, 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.

Where is M42 right now?
M42 is located in the constellation Orion, at right ascension 05h 35m 16s" and declination -5° 23' 22s. At the current time, it is below the horizon and not visible from your location.M42 - Orion Nebula
The Orion Nebula (M42) is a diffuse nebula located in the constellation Orion. It was discovered by Nicholas-Claude Fabri de Peiresc in 1610 and later cataloged by Charles Messier in 1769. M42 is one of the brightest nebulae in the sky and can be seen with the naked eye.
M42 spans about 24 light-years across and contains a rich population of young stars, including the Trapezium, a group of four massive stars. The nebula is approximately 1,344 light-years away from Earth and has an apparent magnitude of 4.0, making it a popular target for amateur astronomers.
