June’s full moon, known as the Strawberry Moon, will come the same day the moon reaches the closest point in its orbit around the Earth, called perigee, creating a “supermoon” on June 14 at 7:51 a.m. Eastern Daylight Time in New York (1152 UTC) according to the U.S. Naval Observatory.
For observers on the east coast of North and South America, the moon will be below the horizon when it is officially full, as the moon sets at 5:09 a.m. in New York, 6:21 a.m. in Miami, and 6:32 a.m. in Rio de Janeiro (all times are local).
The moon reaches perigee at 7:23 p.m. Eastern Daylight Time on June 14 according to the sky-watching site In-the-sky.org. At perigee, the moon appears about 10 percent larger than average — a “supermoon.” On average the angular diameter of the moon is about 31 arcminutes — a bit more than half of one degree. One degree is about the size of a pinky finger held at arm’s length, and an arcminute is 1/60th of that. The “supermoon” is about 33.5 arcminutes. Even though the name sounds like it should be really large, it takes a very observant skywatcher to tell the difference.
The moon appears larger because its orbit is an ellipse rather than a perfect circle. At perigee, the moon will be 222,098 miles or 357,432 kilometers from Earth, per heavens-above.com calculations. The average distance between the moon and Earth is …
