OBJECT GUIDE
Mercury tonight
The Sun’s closest companion — a quick twilight catch most people have never knowingly seen.
Mercury tonight is only ever a twilight object: it hugs the Sun, so look low above the western horizon shortly after sunset or the eastern horizon before sunrise, during the few weeks around each greatest elongation. It is surprisingly bright — the challenge is the twilight glow and the low altitude, not faintness.

How to spot it
Mercury isn't well placed tonight from New York — here's what works whenever it returns to the night sky.
Catch it in twilight
Scan low above the horizon on the Sun’s side of the sky — west after sunset or east before dawn. It looks like a lone, moderately bright star in the glow.
Sweep the glow
Binoculars pick Mercury out of bright twilight before your eyes can. Wait until the Sun is fully below the horizon before raising them.
Expect a tiny phase
A small scope shows a minute Moon-like phase, shimmering through thick low-altitude air. The phase, not surface detail, is the prize.
Why look at Mercury
A genuine bragging right
Most people have never knowingly seen Mercury — catching it is a small victory.
No gear required
In clear twilight it is a naked-eye object, if you know exactly when and where.
A fast-moving target
It swings between the evening and morning sky in weeks, so every apparition is a fresh chase.
Quick facts
Common questions
Why is Mercury so hard to see?
Because it orbits so close to the Sun, it never strays far from it in our sky. That means Mercury only appears low in twilight — shortly after sunset or before sunrise — and never against a fully dark sky.
When is the best time to catch Mercury?
During the couple of weeks around each greatest elongation, when it stands farthest from the Sun. In an evening apparition, look west roughly 30–60 minutes after sunset; in a morning one, look east before dawn. The tonight pages give exact times per city.
Do I need equipment to see Mercury?
No — in clear twilight with an open horizon it is naked-eye visible. Binoculars make the search much easier, but never sweep with them until the Sun has completely set.
What does Mercury actually look like?
A steady, moderately bright star-like point low in the twilight glow, often with a slightly warm tint from the thick air near the horizon. Telescopes show a tiny phase, like a miniature Moon, but no surface detail.
