The crescent moon has a planetary companion called Saturn, as seen in Starwatch.
The moon undergoes a noticeable change in just one week. Previously, it appeared as a decreasing crescent in the morning, but now it appears as an increasing crescent in the evening twilight.
The percentage of the moon’s visible surface that is illuminated has remained consistent at 14%, in contrast to last week’s 12.7%. However, this time it is the eastern hemisphere of the moon that is illuminated, rather than the western hemisphere. Last week, the moon was accompanied by Mercury and Venus, but this week it is Saturn’s turn.
The graph depicts the western view from London at 1700 GMT on January 14th. Begin your search for Saturn shortly after sunset when the sky begins to darken. Although Saturn is nine times larger than Earth and has reflective clouds, it will still appear faint due to its distance of 1.6 billion km from our planet.
Around 7 PM GMT, the sky will be completely dark, but Saturn will be noticeably lower in the sky. Those who are able to see it will observe a distinct yellow hue. The alignment can also be easily spotted in the western evening sky from the southern hemisphere.
