How one can see the planet Mercury at its biggest western elongation

January 30, and the times simply earlier than and simply after that, shall be time to attempt to see Mercury as a result of it’s at its biggest western elongation. You gained’t want a telescope for this, however you could have to get up early. Additionally, the Southern Hemisphere will get a greater view than the Northern.

However when an inferior planet is at or close to one among its “biggest elongations” (every inferior planet has an jap and a western “biggest elongation”) you’ll have an honest shot at seeing it. As a result of it is at a degree of biggest (deep breath) angular separation from the Solar relative to Earth — so it is not essentially on the biggest distance from the solar in its total orbit, however that is what it seems to be prefer to us Earthlings, and due to that, it’ll appear brighter, and can look that approach for longer.

How can I see Mercury at its biggest western elongation?
