Every year from July 17 to August 24, the earth passes through perseus. The perseid meteor shower is one of the three largest meteor showers in the northern hemisphere. The perseid meteor shower is large and stable, and the scenery is spectacular. For details of this year’s perseid meteor shower, please see below.
Although the highest peak is on August 12-13, you should be able to see meteors as long as you pay close attention to the night before and after the peak.
Viewing location: It can be seen in the northern hemisphere. Choose a place with less light 觀星推介 and a wide field of vision to see the sky full of stars.
Every year from July 17 to August 24, the earth will pass through the orbit of comet Swift Swift-Tuttle, the father of the perseid meteor shower.
Fragments of the comet are in its orbit, but we won’t be able to cross the dense part of the orbit until the first week of August.
Debris from Comet Swift-Tuttle hits the upper atmosphere of the Earth at a speed of about 130,000 miles (210,000 kilometers) per hour, and the fast-moving perseid meteor will light up the night sky.
If the earth happens to pass by an unusually dense meteoroid (celestial fragments). ), we will see an increase in the number of meteors.
Comet Swift-Tuttle has an eccentric (not round but long) elliptical orbit, her aphelion is outside the orbit of pluto, and the perihelion is within the orbit of the earth. Comet Swift-Tuttle has an orbiting period of about 133 years. Whenever she passes through the inner solar system, the sun warms and softens the ice in the comet, allowing her to release fresh comet material into its orbit.
The last time Comet Swift-Tuttle reached perihelion was in December 1992, and the next time it will be in July 2126.
We cause the perseid Meteor Nebula to happen every year. Their mother comet Swift-Tuttle takes about 130 years to orbit the sun. The last time she orbited the sun was in the 1990s, when she was still far away from the sun. But every year when the earth crosses her comet orbit, the comet left by Swift-Tuttle shatters.
