M45 - Pleiades
The Pleiades (M45), also known as the Seven Sisters, is an open cluster located in the constellation Taurus. It has been known since antiquity and was later cataloged by Charles Messier in 1771. M45 is one of the nearest open clusters to Earth and contains a bright population of stars.
M45 spans about 17.5 light-years across and contains over 1,000 stars. The cluster is approximately 444 light-years away from Earth and has an apparent magnitude of 1.6, making it visible to the naked eye under most skies.

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 M45 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.
