Help to spot Mercury tonight!
Mercury is a tricky little blighter to spot. Its the closest planet to the Sun at an average distance of 57.9 million km. Due to its proximity to the Sun it can be somewhat challenging to find as its always low in the morning sky just before sunrise or evening sky just after sunset. Fortunately tonight, help is at hend.
There are a couple of prominent stars in the constellation Gemini called Castor and Pollux which tonight, will be low in the west about an hour after sunset. Looking West you can see Castor on the right and Pollux to the left. Mercury then extends the line out to the left. You’ll need a good clear western horizon to spot it though.. Good luck.
