A supermoon happens several times a year, not just once in a while.

Quick answer

Astronomers and NASA-style definitions generally say:

  • A supermoon (full Moon near its closest point to Earth) occurs about 3–4 times per year.
  • That means you see a supermoon roughly every 3–4 months , often in consecutive months when they do occur.

What counts as a supermoon?

  • The Moon’s orbit is slightly elliptical, so sometimes it is closer to Earth (perigee) and sometimes farther away (apogee).
  • A supermoon is usually defined as a full Moon that happens when the Moon is within about 90% of its closest distance (perigee).

How often, in practice?

Looking at typical years:

  • Of the 12–13 full moons in a year, about 3–4 are supermoons.
  • Lists of recent and upcoming dates (2023–2028) show clusters of 3–5 supermoons in a year , often on back‑to‑back months.

So if someone says “supermoons are rare,” that is a bit misleading: they are special but fairly regular , happening multiple times most years.
