It is expected that on July 13 at 12:09 Moscow time, the Moon will be in perigee - the closest point of its orbit to the Earth. The distance between the planet and the satellite will be 357,263 km. At the same time, a little more than 9.5 hours later, at 21:38 Moscow time, a full moon will occur.
"The apparent diameter of the moon [on this day will be] 33 minutes 27 seconds. <...> On July 13, the full Moon will appear above the horizon after 21 hours and around midnight will reach its maximum height above the southern horizon. All night, until sunrise, the supermoon will shine in the constellation Sagittarius, " the planetarium announced TASS.
If the weather is clear, you can also see two planets in the sky that will accompany the supermoon - Saturn and Jupiter. Three stars of the Summer Triangle will shine above the full Moon, and to the right - the star Arcturus from the constellation Volopas.
A supermoon is the moment when the full Moon approaches the Earth at a distance closer than 362,000 km and the moments of the passage of the perigee and the full moon are no more than three days apart in time. Coincidences of these two moments (perigee and full moon) occur every year, but close coincidences (less than 9 hours) they are quite rare. On July 13, 2022, the difference between the perigee and the full moon will be slightly more than 9.5 hours.
