Vietnam will welcome super moon at any time in 2018?

In 2017 there is only one super moon, but by 2018 there will be 2 super moons. In fact, the next two full moons appear in January 2018 - will be super moon. So when will Vietnam receive the super moon?

When will the next appear?

By definition of astrologer Richard Nolle, or has moved to the distance of 362,146km (225,027 miles) of Earth, measured from the center of the Moon and Earth, to be considered super moon.

On January 2, 2018, we will welcome the super moon again.

Based on this definition, 2017 has only one super moon, the full moon in December. Super moon on December 3 , 2017 is the first super moon in three super moons. Two full moons in January 2018 - will appear on January 2 and January 31 - also considered super moon. As is the case, it is the second super moon among the three super moons that completely coincides with the time when the Moon is at its extreme position (the Moon's closest point to Earth in that month). Therefore, in this three-moon series, the super moon on January 2, 2018 will appear in the nearest and largest position.

1. Distance from full moon (takes place at 15:47 UTC, December 3, 2017): 357,987km. Distance of the extreme position on the Moon (takes place at 08:42 UTC, December 4, 2017): 357,492km.
2. Full moon distance (takes place at 02:24 UTC, January 2, 2018): 356,846 km. The distance of the extreme position on the Moon (taking place at 21:54 UTC, January 1, 2018): 356,565km.
3. Full moon distance (takes place at 13:27 UTC, January 31, 2018): 360,199km. The distance of the extreme position on the Moon (takes place at 9:54 UTC, January 30, 2018): 358,995 km.

Some will call the full moon appear on January 31, 2018 (a concept in the Western world that indicates the full moon phenomenon does not match a calendar month. Usually a calendar year is twelve times full moon, equivalent every month there is a full moon) because this is the second full moon in the same month.

We can expect super moon in the next third to recur after the 14th lunar month (14 times the full moon). By the way, the 14th lunar month represents the period of 1 year, 1 month and 18 days.In 2019, the second super moon in three super moons will appear - the nearest and largest super moon.

What does super moon look like?

Most astronomers think that you can't detect any difference with the naked eye between a super moon and any normal moon, although some observers say you have can.
