在这张傍晚的天空景观中，只有水星从太阳系的行星游行中消失了。明亮的火星几乎在太阳的对面升起，在最左边。其他肉眼可见的行星木星、土星和金星也可以被发现，过于暗淡的天王星和海王星的位置在黄道平面的弧形痕迹附近被标记出来。日落后，在最右边靠近西方地平线的是一个年轻的新月，它的表面部分被地球的阳光照亮。在1月2日拍摄的合成全景图的前景中，地球由埃特纳火山下部的西尔维斯特里陨石坑代表。当然，在整个1月份，地球傍晚的天空都布满了行星。1月13日，对于美国大陆和加拿大东部的天文爱好者来说，一个接近满月的月亮将出现在火星前面。

Only Mercury is missing from a Solar System parade of planets in this early evening skyscape. Rising nearly opposite the Sun, bright Mars is at the far left. The other naked-eye planets Jupiter, Saturn, and Venus, can also be spotted, with the positions of too-faint Uranus and Neptune marked near the arcing trace of the ecliptic plane. On the far right and close to the western horizon after sunset is a young crescent Moon whose surface is partly illuminated by earthshine. In the foreground of the composite panorama captured on 2 January, planet Earth is represented by Mount Etna's lower Silvestri Crater. Of course Earth's early evening skies are full of planets for the entire month of January. On 13 January, a nearly Full Moon will appear to pass in front of Mars for skywatchers in the continental U.S. and Eastern Canada.
