There will be a "Supermoon" and more meteor showers in August, according to NASA

There will be a

The Perseid meteor shower will have its days of greatest visibility during the second week of next August, specifically from 11 to 13.
But an important competitor has emerged. It will coincide with another celestial phenomenon: "the Supermoon", according to NASA.
The natural satellite of the Earth will acquire its apogee; It will be the biggest and brightest full moon of the year. According to astronomers, it will appear in the sky on August 10. "This is bad news for the Perseids," reports Bill Cooke of NASA's Office of the Environment on Meteorites.

Typically in the Perseids you can see about 100 meteors per hour, but they will have to compete with a full moon 14% larger and 30% brighter than normal. "The lunar glow erases the velvety black backdrop required to view faint meteors and dramatically reduces trails," adds Cooke. The Perseid meteors will come from Comet Swift Tuttle, which every 133 years undertakes a journey through the inner solar system leaving behind a trail of dust and sand. When the Earth passes through the debris zone, the comet particles hit the atmosphere,
disintegrating below and leaving the bright flashes of light that we enjoy in the sky.

But there's good news for viewers too, Cooke says. Comet Swift Tuttle's stream of debris is wide and it will be possible to see Perseids in late July, long before the Moon is full. “Anyway, the Perseids are rich in fireballs brighter than Jupiter or Venus. These will be visible despite the full moon ”, he asserts.
