The "worm super-moon" will illuminate the night of this Wednesday

This week, you can see the "worm super-moon", the third and last phenomenon of this kind that we will enjoy this year.on the night of March 20 in the Western Hemisphere and the early hours of March 21 in the Eastern Hemisphere, reports EarthSky.

It is so called because in the northern hemisphere of the planet ends winter, the ground thaws and worms begin to appear on the ground. Native Americans would have created this name because they used our satellite as a reference for seasonal changes.

The event sthis will happen a few hours after the arrival of the equinox – with which this did not coincide since 2000 – and this will not happen nearly simultaneously until 2030. Thus, this Wednesday, the Moon will appear 30% brighter and 14% larger because it will reach its closest point to the Earth.

NASA says that when that happens, the Moon influences the tides and can cause significant problems in some coastal areas, especially if the weather adds big waves or storms, because of the low air pressure on the affected area.

This event It is also known as the "sap super-moon" because it appears on dates close to the beginning of spring. in many countries of the North of the Earth and mark the pbadage to a season in which the fields become green.

In the southern hemisphere, it will be the first moon of autumn or 'supermoon harvest'.because in this season harvests are collected.

In February, the "Big Snow Moon" was cataloged as the largest and brightest full moon of the year., features that can not be seen before 2026.

The term "supermoon" was introduced by astrologer Richard Nolle in 1979 and it specifically refers to a full moon brighter than usual.

The February super-moon was believed to be the largest and brightest full moon of the year due to the almost exact superposition of the perigee of the moon.

As you go the moon orbits in an ellipse, its nearest point, the perigee, will come very close to the Earth. The farthest point of the ellipse is called the climax, in its 28-day lunar cycle.

This point is reached when the moon coincides perfectly with the most complete version of the moon, which means that It appears to be 14% larger and 30% brighter than normal.

A small asteroid the size of a house will pbad very close to our planet, producing the closest approach to 23:01, Argentina time. from the 21st of March next. L & # 39; asteroid He had been discovered very recently, March 9 pbaded from Mount Lemmon in Arizona, and he was designated with the name of 2019 EA2.

According to NASA estimates, the minimum approach will be given at a distance of 306,363 km from the Earth, which corresponds to less than the distance that separates the Earth from the Moon (0.8 lunar distance).

The asteroid has an estimated size of 23 meters in diameter. On February 15, 2013, an asteroid of similar size (17 meters) crossed the Chelyabinsk skyline in Russia, causing a shock wave that broke the windows of six Russian cities and forced 1,500 people to see a doctor.

2019 EA2 travels the space at a speed of 19,336 km / h compared to the Earth. Its orbit moves between the orbits of Venus and Earth, which should be the closest encounter for the next 112 years.since we will have to wait until March 2131 to find it so close to our planet.
