You may have seen an unusually large moon in the sky over night.
Because our celestial neighbor is relatively close to Earth, these full moons will appear to be unusually large. That distance varies because the moon follows an elliptical orbit. When it’s close and full, it appears bigger and brighter than normal, although the difference can be hard to detect.
The full moon Saturday may have seemed huge, but it was an illusion caused by its position in the sky.
Two other supermoons will come later this summer on Aug. 10 and Sept. 9.
