M105 Observation Details
M105 Daily Motion
M105 will be visible until June, 27, 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.

M105 - Elliptical Galaxy
M105 is an elliptical galaxy located in the constellation Leo. It was discovered by Pierre Méchain in 1781 and later cataloged by Charles Messier. M105 is known for its bright core and lack of spiral arms.
M105 spans about 55,000 light-years across and contains a massive population of old stars. The galaxy is approximately 36 million light-years away from Earth and has an apparent magnitude of 10.2, making it visible with a small telescope.

The graph is structured with the vertical axis showing the hours of the day, ranging from 12 AM to 12 AM the next day, while the horizontal axis spans each day of the year.
The reddish shaded area indicates the periods when the M105 is above the horizon, visible to observers. The white line marks the times when the celestial object reaches its highest point in the sky each day, known as the transit.
