The size of the super moon is up to seven percent larger and 15 percent brighter than a typical full moon. According to Space.com, the full moon measures approximately 31 minutes of arc, or 0.52 degrees wide in the night sky on average, and on May 7, it will have approximately 33 minutes of arc (0.55 degrees). A closed fist can give you the reference because it measures about 10 degrees wide at arm’s length.
Binoculars and telescopes are not specifically required, but these tools can give you a clearer view and more details of the moon. Unlike observing the sun, there is no harm in looking at the moon with our bare eyes.
For 2020, the four full moons from February to May reach this 90% threshold, with the largest and brightest full moon falling on April 8.
While a super moon is considered less serious and scientific than an eclipse, it represents a chance to encourage people to start looking at the moon. The next super moon will not happen before the end of April 2021.
