Tonight, Vietnam catches a meteor shower as the three planets align after 800 years.

According to the HCMC positioning of the page Time and date, the Ursid meteor shower, the last meteor shower of the year, will peak on the night of the 22nd and dawn on the 23rd Vietnam time. However, it began to fall from December 17 and for tonight on December 21 it is enough to enter the “gravitational” phase, with about 10 meteors per hour.

The name Ursidas comes from the constellation Ursa Minor, or Little Star, which is also where the meteor shower will be emitted. So, to see the most beautiful shooting stars, locate this constellation. Ursid shooting stars are actually small objects in the dusty tail of Comet 8P / Tuttle, although they appear to have shot up. Earth flies through this tail once a year, creating a meteor shower.

The night of December 21 is also a special occasion. According to the POTIt would be the rare three planets Earth, Jupiter and Saturn, the region with the Sun, aligned in a straight line. The last time this event took place was in the Middle Ages, 800 years ago.

At the alignment point, Jupiter and Saturn are closer to Earth, so they look huge and clear even to the naked eye. If in the days before, Jupiter and Saturn seemed like a strange couple next to each other, very close, then on the 21st night, it would almost collapse into a single giant planet.

These 2 planets have many moons, including those larger than Mercury and Pluto, so with a personal observation tool you can see 4 moons of Jupiter and 2 moons of Saturn.

Bed sheet Earth Heaven experts advise everyone to try to keep their eyes accustomed to the dark for 15 to 20 minutes before observing to see planets and meteors more clearly. This is quite a convenient night of contemplation because the objects are not overwhelmed by the moon.
