Key Takeaways:

  • Astronomy magazine highlights an upcoming favorable viewing opportunity for the planet Mercury.
  • Mercury's observation is infrequent due to its proximity to the Sun and resulting low altitude in the sky.
  • The last week of June presents a window of opportunity for observing Mercury.
  • Visual observation is suggested, with binoculars recommended if naked-eye viewing proves challenging.

In this episode, Astronomy magazine Editor Dave Eicher invites you to head out sometime soon and observe the planet Mercury in the evening. Mercury, the closest planet to the Sun, only pokes above the horizon several times each year. And it never gets far from the Sun, meaning it doesn’t get high in the sky. The last week of June, however, is a time when you can go out and spot it. You should see it with your naked eyes, but, if not, use binoculars. Good luck!
