|2018-January Mercury ⬅︎|
| This month viewing will be best around the start of the month in dawn twilight in the SE sky (see above). This is because Mercury reaches maximum elongation on January 1st when it will be 22 degrees west of the sun.
Mercury is a challenging planet to view. As the closest planet to the sun, it is most often in our sky during daylight hours and sunlight overpowers it.
As Mercury goes around the sun its angular distance from the sun in our sky, or elongation, changes rapidly. It reaches a maximum about every two months and Mercury may be visible in dawn or evening twilight for a few days around this time. Mercury is never visible at night.
Binoculars & Telescope
Binoculars can make it easier to spot Mercury. Since Mercury goes through phases like our moon, a telescope can be used to view the current phase. Warning: never use optical aid to view at dawn since the sun might rise while viewing and cause severe eye damage.
